Two Finger Trigger Pull? The 128 Correct Answer

The Remington Model 700 bolt-action rifle was first produced in 1962. It was one of the best-selling bolt-action rifles in the United States for most years of its production. Over 7 million rifles were made and a high percentage of such rifles are still in use today.

After World War II, Remington searched for a new production rifle that would be a hit in the post-war era. Merle “Mike” Walker patented a new fire control that was originally included in the design of a new consumer rifle: the Model 721. The patent was for a unique new fire control with a floating part called the “trigger connector” that simply attaches to the main body of the rifle with a spring deduction. Otherwise, the trigger connector will float and separate from the main trigger body with each shot of the rifle.

Here is a drawing of the Model 700 internal fire control with various components labeled:

problems with the deduction

Problems surfaced almost immediately. Even before production began, Mr. Walker reported a “theoretically unsafe condition” to Remington officials. This 1946 report quickly led to another in 1947, which clarified that it “is possible to fire the gun by pressing the safety in the off position.”

In the many years since, the theoretically unsafe condition has resulted in literally thousands of customer complaints that the Model 700 (and related models) will deploy under any of the following circumstances:

When the rifle’s mechanical safety is shifted from the “safe” to the “fire” position (as described in the 1947 report mentioned above)

When the rifle’s breech is tampered with in the closed position

When the rifle’s breech is opened

If there is a jarring movement of the gun

Other bolt-action firearms have the same problems, and the trigger in question is commonly known as the “Walker Fire Control” after its inventor. Although Mr. Walker has testified that he never intended the fire control in question for consumer rifles, it has nonetheless been fitted to a variety of consumer rifles including the Model 7, 721, 722, 725, 700, 710, 715, 770, 660, 673, 600, Sportsman 78 and XP100.

Remington recall

Since the introduction of the Walker Fire Control, Remington has received thousands of customer complaints and hundreds of lawsuits or claims for personal injury. In each case, Remington has dismissed the claims as erroneous and has called for a variety of explanations, including that the handler must have inadvertently pulled the trigger. However, Remington issued a recall of the Model 600 and 660 in the late 1970s following an accident and serious injury in Texas.

After further investigation, Remington concluded that a high percentage of such rifles, also equipped with fire control very similar to the Model 700, would fire without pulling the trigger. However, after a similar investigation found that only a small percentage of Model 700s could experience a similar malfunction, Remington decided to just better educate customers about firearm safety. Therefore, Remington continued to manufacture the Model 700 without modifications, knowing full well that thousands of users were at risk.

The replacement trigger

Complaints continued to come in, and sometimes the company received a customer complaint of a misfire almost every business day. In 2004, Remington introduced a replacement trigger commonly known as “The X Mark Pro”.

Most telling about the new trigger was that Remington eliminated the trigger connector. Remington officials have even confirmed in affidavits that the new design was in response to “the lawsuit” against Remington, which focuses on the dangerous and defective condition of the trigger connector.

Remington Class Action Settlement

In 2017, the U.S. District Court for the Western District of Missouri approved a class action lawsuit that would result in the retrofit of all existing Model 700s, as well as a high percentage of related rifles. Some older rifles cannot be repaired and would receive little monetary compensation. While it is now up to the consumer to return their rifle in exchange for the X Mark Pro, any consumer has the right to do so free of charge.

Voluntary recall of X Mark Pro

During the final phase of negotiations for the Model 700 retrofit, Remington announced a voluntary recall of the X Mark Pro. This recall, which was then considered by class counsel and the court, was due to a manufacturing defect in the assembly of X Mark Pro rifles.

Small amounts of a glue-like substance called “Loctite” are added during assembly to ensure certain screws stay in place and cannot be removed or adjusted. Unfortunately, in some Remington installations, too much Loctite was added, resulting in extra amounts leaking into the fire control and essentially “gluing the work together”. This, too, resulted in unintentional and unexpected firing, which in many ways duplicated the Walker Fire Control experience.

While many individuals get their guns repaired, many others will not. Tragically, those who continue to use dangerous guns risk a ticking time bomb of malfunctions. Not every gun will fail, but every gun is designed so that failure is a definite reality.

In my February 22nd post about the new Weatherby Vanguard Series 2, I mentioned that Weatherby had given it a two-stage trigger, and blogger Ripper III asked what the benefit of that was? Good question.

People who design triggers need to design a mechanism that does two contradictory things. It has to have enough sear engagement (there has to be enough contact between the sear and the trigger) so it doesn’t fire, cock, or go off at the mere touch, because when those things happen, there’s product liability. Lawyers and TV reporters come running.

But if you have enough Sear engagement to prevent all of these things, you’ll end up with a heavy, sluggish, spooky trigger. For more than 20 years, American gun manufacturers were so afraid of accidental discharge lawsuits that the triggers that emerged were almost invariably heavy, sluggish, and scary.

There didn’t seem to be a solution until 2002 when Savage introduced the AccuTrigger, which modernized an old style of trigger design – the two-stage trigger. A two-stage trigger requires two separate “pulls” or mechanical actions before the sear can release the firing pin. To oversimplify things, this means that the sear is held at two points instead of one, and unless both are released the rifle cannot pop.

It also means the second phase of the draw can be smooth, light and crisp without the risk of accidental discharge. The two-stage trigger was ignored by civilian designers over the years because it was unfashionable. In the decades when Springfields, Mausers, and Enfields were being sported by pallet loading, the first thing a gunsmith did was convert the two-stage trigger to a single-stage. A great many fine trigger pulls were lost in this way. I have a sportier ’03 Springfield with an intact two-stage trigger. Its owner was a very accomplished gunsmith who could easily have altered it, but he sensibly left it alone, and none of the many, many deer he took with him seemed to mind.

A two-stage pull is no guarantee of a good trigger. I’ve shot a lot of military rifles with rotten double-stage triggers, and I’ve pulled some really mediocre specimens from under the new civilian double-stage triggers. If the design isn’t solid, or if the trigger is poorly made, it will still be a bad pull.

But the good ones are really good.

diagnosis

The diagnosis of the trigger finger does not require any complex tests. Your doctor or healthcare provider will make the diagnosis based on your medical history and a physical exam. During the physical exam, your doctor will ask you to open and close your hand and check for areas of pain, ease of movement, and signs of locking.

Your doctor will also palpate your palm to see if a lump is present. When the nub is connected to the trigger finger, the nub will move as the finger moves because the nub is a swollen area in part of the tendon that moves the finger.

treatment

Treatment for trigger finger varies depending on its severity and duration.

medication

Nonsteroidal anti-inflammatory drugs — such as ibuprofen (Advil, Motrin IB) or naproxen (Aleve) — can reduce pain, but are unlikely to reduce swelling that is narrowing the tendon sheath or pinching the tendon.

therapy

Conservative non-invasive treatments may include:

Rest. Avoid activities that require repetitive grasping, repetitive grasping, or prolonged use of vibrating hand-held machines until your symptoms improve. If you cannot avoid these activities entirely, padded gloves can provide some protection.

If you cannot avoid these activities entirely, padded gloves can provide some protection. A rail. Your doctor may ask you to wear a splint at night to keep the affected finger in an extended position for up to six weeks. The splint helps to rest the tendon.

Surgical and other procedures

If your symptoms are severe or conservative treatments have not helped, your doctor may suggest:

steroid injection. Injecting a steroid drug near or into the tendon sheath can reduce inflammation and allow the tendon to slide freely again. This is the most common treatment and usually works for a year or more in most people treated. But sometimes it takes more than one injection. In people with diabetes, steroid injections tend to be less effective.

Percutaneous release. After numbing your palm, your doctor will insert a sturdy needle into the tissue around your affected tendon. Moving the needle and your finger helps break up the narrowing that is blocking the smooth movement of the tendon. This treatment can be done under ultrasound guidance so the doctor can see where the needle tip is under the skin to ensure the tendon sheath is opened without damaging the tendon or nearby nerves. This procedure is usually performed in the doctor’s office or in a treatment room.

Surgery. Through a small incision near the base of your affected finger, a surgeon can cut open the narrowed section of the tendon sheath. This procedure is usually performed in an operating room.

Questions your doctor might ask include:

In this resource, we cover the difference between Single Action and Double Action, which we touched on briefly in other resources such as Hammer vs. Striker. Being single action and double action, these terms fall mostly within the hammergun world, although there are some exceptions to this rule. But for now, let’s just deal with hammer-fired firearms.

An easy way to remember the difference between single action and double action is to remember that a single action trigger only performs a single action, dropping the hammer, which fires the cartridge, and a double Action Trigger performs two actions in one trigger pull: cocking the hammer and then releasing it.

It should be noted that with semi-automatic pistols the hammer is cocked by the recoil slide and does not have to be cocked manually after the first shot.

SINGLE ACTION

We’ll start with single action because that’s where firearms historically got their start. Using the technical definition of single action, black powder rifles and muskets that predated revolvers were single action, requiring the shooter to manually retract the hammer before pulling the trigger. So it’s easy to understand that when it comes to revolvers, single-action means one trigger pull equals one round fired, and that’s it. The shooter must then cock the hammer to fire the next round.

If you’ve seen old Western movies showing midday showdowns, you’ll recognize these revolvers as single-action revolvers, where the shooter had to retract the hammer before firing each round. The advantage of a single-action firearm is that the trigger is both light and short. This allows you to pull off the round without having to exert a lot of force through your hand, which could affect your accuracy. Because of this benefit, many people find single-action triggers easier to shoot and a smoother experience. The downside is that when using a single-action revolver, you have to cock the hammer before each and every shot.

Single action semi-automatics are still the same as far as 1 trigger pull = 1 shot fired and the hammer needs to be manually retracted before the first shot, but they differ from single action revolvers in that recoil is controlled by the round fired Cock the hammer for follow-up shots. This allows the shooter to eliminate the step of manually retracting the hammer before each shot, allowing subsequent shots to be laid quicker than with a single-action revolver. Because of the light trigger pull on single action, many people who have trouble with the heavier trigger pull on double action find these firearms much easier to shoot since they don’t have to use as much force on the trigger.

DOUBLE ACTION

With double-action triggers, the difference between revolvers and semi-automatics becomes more apparent as follow-up shots are handled.

A double-action revolver has a trigger that both cocks and releases the hammer in one pull, and this occurs with every shot unless the hammer is manually retracted before the shot is fired. If the double action is used with the revolver every time, the trigger pull will be consistent on each shot and have the same trigger length and weight. This allows the shooter to get used to the trigger faster because it behaves the same way with every pull.

However, most double-action semi-automatics are built as DA/SA, which is double-action to single-action. This means that the first round fired is a double-action trigger, where the trigger both cocks and releases the hammer in one pull, and then each subsequent shot is a single-action. The way this works is that firing the cartridge causes recoil that pushes the slide back, ejecting the spent casing and chambering a new cartridge. At the same time, this recoil resets the hammer and arms it for the next shot, eliminating the need for the shooter to manually cock the hammer or resort to double-action trigger movements again. This allows all shots from 2nd and up to be shorter and lighter single-action moves.

There are some firearms that are DAO (Double Action Only), but you won’t come across them all that often in the semi-automatic world. Just understand that any semi-auto that says it’s DAO means every trigger pull has a double action. That is, heavy and long, because it performs both actions as described above.

WHAT IS THE BEST?

As with most things as diverse and diverse as firearms, there really is no “best” when it comes to single-action vs. double-action. It’s mostly down to personal preference as everyone is built differently. Just as someone incredibly tall might have trouble enjoying the ride in a tiny car, there will be individuals who won’t enjoy one type of action over the other. Additionally, the action types feel different, and it’s up to you to determine what feels best in your hands so you can practice properly and efficiently with your weapon to become proficient. You don’t want to buy something that requires you to change your routine or relearn a habit every time you venture into the area.

Some people find it difficult to get used to a DA/SA trigger because that first shot always requires more power than anything else that can throw them off their first shot. Others, on the other hand, enjoy owning a DA/SA firearm because they like to carry a firearm that makes a more deliberate initial trigger pull so they are safer with a round in the chamber without having to keep the hammer “locked and cocked” all the time .

On the other hand, single action can be good when you want to practice your accuracy and shot placement and make each shot a conscious action that you need to prepare before each shot. And as mentioned, a single-action trigger is much easier to use and usually allows for better accuracy since the hand moves less during the trigger pull.

Overall, it’s always best to try many different types of firearms to determine which one best suits your hands, style, and needs. You want to make sure you’re able to practice with your gun to feel comfortable and proficient with it – and to do that you need to both enjoy shooting it and be safe every time you take it out be to serve them.

I was fortunate to grow up surrounded by very experienced shooters who taught me a great deal about firearms, and one thing that all of these firearms enthusiasts shared was a genuine dislike of factory triggers. Today, however, firearm manufacturers have greatly improved their trigger mechanisms, and the triggers in modern firearms are safer, smoother, lighter, and easier to use than those that were standard in most production firearms just 30 years ago. In many cases, such as For example, on centerfire hunting rifles, externally adjustable factory triggers can be lowered to pull weights in the 2 pound range – sometimes even less – all without having to make a trip to your local gunsmith.

But are lighter triggers always better? It depends on the shooter, the weapon, and what the weapon is going to be used for.

How triggers work

Triggers are mechanisms that release either a hammer or a firing pin. When released, the firing pin or hammer, on modern cartridges, drives the firing pin into the primer and fires the round. In handguns, the trigger function is often referred to as “single action” or “double action”. Single action triggers, such as those found in the Colt 1911 and clones and some revolvers, serve one purpose – to fire the hammer so it can move forward and fire the primer. Double-action triggers serve two purposes: they cock the hammer and release the hammer once that is complete. Firing pin fired semi-automatic pistols use operating systems where pulling the trigger completes the cocking process and releases the firing pin to initiate the shot.

In general, the less work a trigger does, the lighter the pull. Bolt-action rifles, pump-action and semi-automatic shotguns, and single-action pistols all have an easy trigger action because the trigger does only one job – releasing the firing pin or hammer. Double-action revolvers and semi-automatics have a longer, heavier trigger because the trigger serves to cock and release the hammer. Striker-fired semi-automatic trigger pulls generally fall somewhere in the middle in terms of pull weight, and striker-fired guns have longer trigger travel than most single-action firearms.

Classification by weight

The best way to reduce trigger pull is with weight. Here’s a breakdown of different firearm weight ranges by pound of trigger pull:

1.5 to 5 pounds: single action revolvers and semi-automatics, target rifles, hunting rifles, shotguns

Light trigger movements are required for some applications, mainly target shooting. If you’re trying to hit steel plates at half a mile with your scoped bolt-action rifle, you’ll need to do whatever it takes to steady the gun on aim, and that starts with a lightweight, non-tracking (meaning there’s very little to take) . -up or movement before shooting) trigger design. Long-range rifles and some competition pistols (like “race guns,” which are semi-automatic machines designed for competition) will be at the lower end of this weight class, with triggers ranging from about 1.5 pounds to 3 pounds. Many weapons of this class have an external security system. The 1911 semi-automatic pistol actually has two external safety devices – a manual safety and a grip safety – which is one of the reasons many shooters feel comfortable carrying 1911s for duty or personal protection, even if the guns are very light have 3 pound deductions. At the higher end of that weight class you have pump action and semi-automatic shotguns, which tend to have heavier triggers in the 5 pound class (or sometimes higher). This is partly because shotguns rarely require a very light, creep-free trigger. When shooting clay targets, upland birds, or waterfowl, it’s more of a trigger “clap” than the steady pull of a target rifle trigger, so a slightly heavier shotgun trigger makes sense for many applications.

5 to 8 pounds: Striker-fired semi-automatics, shotguns, some rifles

Most firing pin semi-automatic pistols have trigger weights that range between 5 and 7 pounds, and these trigger devices generally have some take-up. This shot is actually used to stop cocking the firing pin, and many firing pin fired guns have trigger safety devices that require this shot before firing. You’ll also find some hunting rifles (but very, very few target rifles) in this pull weight class, as well as many shotguns. While 5 or even 6 pounds was a fairly standard trigger weight for hunting rifles just a few years ago, companies have widely improved and lightened their factory trigger designs.

Having a 6 pound trigger in a firing pin fired carry pistol isn’t always a bad thing, especially as many of these pistols have no external safety of any kind. These medium-heavy triggers don’t significantly impede accuracy when shooting quickly at self-defense distances, so this is a perfectly acceptable trigger for semi-auto strikers.

8lb+: Double-action revolvers and semi-automatics

As mentioned earlier, double-action revolvers and semi-automatics have triggers that serve two distinct functions. And while having a strong trigger on a defensive weapon might seem like a compromise, it’s not always a bad thing. Hammer-fired double-action semi-automatics typically have an initial trigger pull in the 10-pound range, but after the first shot is fired, the backward movement of the slide when firing automatically cocks the hammer, allowing the gun’s trigger mechanism to operate in single-action mode and the trigger pull drops to about 4 pounds for subsequent shots. Many of these guns have a decocker button that allows the shooter to safely lower the hammer without firing a round, transitioning the gun from single action to double action. This makes sense for carry and duty weapons, as the first shot requires a dedicated trigger and all subsequent operations offer an easier, smoother pull.

Double-action and double-action-only revolvers are popular for concealed carry, and these guns rarely have a manual external safety. For this reason, a heavy trigger pull – often in the 10+ pound range – makes sense for safety reasons. Not all double-action revolver triggers are created equal, however, and heavy doesn’t necessarily mean uneven and gritty. Many modern DAO revolvers like the Kimber K6S have very light action triggers that travel further than single action and firing pin triggers but are easy to manipulate.

Shotgun with two parallel barrels

A look at the break action of a typical over and under (O/U) shotgun with the breech open and ejectors visible.

A side-by-side shotgun is a break-barrel shotgun with two parallel barrels that can fire two single shots in quick succession or simultaneously.

construction [edit]

Modern double-barreled shotguns, often referred to as doubles, are almost universally break-action, with the barrels folding down at the rear to expose the breech ends for unloading and reloading. Because no back and forth motion is required to eject and reload the shells, double rounds are more compact than repetitive designs such as pump action, lever action, bolt action, or self-loading shotguns.

Barrel configuration [ edit ]

Double-barreled shotguns come in two basic configurations:

Side by Side (S×S) – the two barrels are placed horizontally;

(S×S) – the two barrels are arranged horizontally; Over-and-Under (O/U) – the two barrels are arranged vertically.

The original double-barrelled guns were almost all S×S designs, which was a more practical muzzleloader design. Early cartridge-firing shotguns also used the side-by-side action as they retained the exposed hammers of the earlier muzzle-loading shotguns from which they evolved. When hammerless designs became common, the buck double design was introduced, and most modern sporting doubles are buck double designs.[1]

A key advantage that doubles have over single-barreled bolt-action shotguns is the ability to have more than one choke at a time. Some shotgun sports, such as B. skeet shooting use intersecting targets presented at a narrow range of distances and require only one stage of choke. Other sports, such as clay court shooting, give the shooter targets at different distances and targets that can get closer or farther from the shooter and therefore need to be tackled at different distances. Having two barrels allows the shooter to use a more open choke for close targets and a tighter choke for distant targets, providing the optimal shot pattern at any distance.

The disadvantage lies in the fact that the barrels of a double-barreled shotgun, whether over-under or side by side, are not parallel but slightly angled so that shots from the barrels usually converge at “40 yards out”. In the side-by-side configuration, the weft cord continues its path to the opposite side of the rib after the point of convergence; For example, the left barrel discharge travels down the left side of the rib until it dead center 40 yards (36.58 m) away. After that, the discharge continues to the right. In the over-and-under configuration with a parallel rib, the discharges from both barrels remain dead center, but the discharge from the “under” barrel shoots higher than the discharge from the “over” barrel at 40 yards (36.58 m). Therefore, double-barreled shotguns are only accurate to practical shooting distances, even though the range of their ammunition easily exceeds four to six times that distance.

Side-by-side shotguns are often more expensive and may require more practice to aim effectively than an over-and-under. The off-center nature of the recoil in an S×S gun can make shooting the bodyside barrel a bit more painful compared to an over-and-under, single-shot, or pump-action lever-action shotgun. Gas-powered and blowback-powered designs have less recoil than both. More side-by-side than over-and-under pistols have traditional “dropped” stocks, where the buttstock end curves slightly to the right, making it easier for a right-handed shooter to aim the gun.

Double-barreled shotguns are also inherently safer because anyone present can tell if the shotgun is loaded or ready to fire when the action is broken up, such as at a clay pigeon, trap, or hunting clay spot when another shooter is firing; If the action is open, the weapon cannot fire. Similarly, doubles are easier to inspect to ensure they are loaded than pump action or semi-automatic shotguns, which require the breech to be opened and the chamber closely examined or felt to ensure it is unloaded. With a double pistol (or a single pistol with an interrupting action), it is easy and immediately apparent at a glance whether the weapon is loaded, i.e. has rounds in any chamber (and just as easy to unload). [citation required]

Trigger mechanism[ edit ]

The early doubles used two triggers, one for each barrel, located front to back in the trigger guard. The index finger was used to pull each trigger because two fingers in the trigger guard can cause a very undesirable recoil-induced double discharge. Double-trigger designs are typically set up for right-handed users.[1] With double trigger designs it is often possible to pull both triggers and fire both barrels simultaneously, although this is not generally recommended as it doubles the recoil and hits both the shotgun and the shooter, especially if it was unforeseen or unintentional. Discharging both barrels simultaneously has long been a hunting trick employed by hunters with 8-gauge “elephant” shotguns, firing the two two-ounce bullets at close range for sheer stopping power.

Later models use a single trigger that alternately fires both barrels, called a single selective trigger or SST. The single selective trigger does not allow both barrels to be fired at the same time, as the single trigger must be pulled twice to fire both barrels. Switching from one barrel to another can be done by a clockwork system, where a cam switches between barrels, or by an inertial system, where the recoil when the first barrel is fired switches the trigger to the next barrel. A double-barreled shotgun with an inertial trigger works best with full-powered shotgun shells. Firing low-recoil shotshells often does not reliably toggle the inertial trigger, occasionally resulting in an apparent miss when attempting to pull the trigger a second time to fire the second barrel (this can also happen if the first shell does not fire). In general, there is a method of selecting the order in which the barrels of a single selective trigger shotgun will fire. Commonly this is accomplished by manipulating the fuse, pressing on one side to select the top barrel first and the other side to select the bottom barrel first. In the event that an inertial trigger does not switch to the second barrel when firing low-recoil shotshells, manually selecting the sequence to the second barrel allows the second barrel to fire when the trigger is pulled again.

One of the advantages of double-barreled, double-triggered or selective single-triggered shotguns is that the second shot can be fired almost immediately after the first with just a second trigger pull, without having to manually operate the bolt (which inevitably leads to destabilization of the shot). . weapon from the shoulder position and affects aiming) and can use different chokes for the two shots (provided, of course, that shotgun shells are fired at full power, at least for a double-barreled shotgun with a selective inertial trigger if necessary to toggle the inertial trigger). This can be noticeably faster than a pump-action shotgun, which requires manual pumping of the fore-end to eject and reload the second shot, and potentially faster or no slower than a semi-automatic shotgun (since there is no bolt action). delay reloading of a second grenade). Note, however, that in neither the pump nor the semi-automatic the second shot has a different choke pattern than the first shot, while in a double the two shots are usually with different chokes. Depending on the type of hunt, the right choke for the shot is always at hand. For example, when hunting birds in the field, the first shot is usually closer than the second because the bird flies away from the shooter. so the more open choke (and barrel) would be better for the first shot, and if a second shot is needed while the bird flies away, the more closed (and hence greater spacing of an effective shot pattern) choke (and barrel) is then appropriate. Conversely, on a driven hunt where the birds are being herded toward the shooter, the closed choke (and barrel) (longer effective distance) should be fired first, saving the open (less effective distance) choke (and barrel) for now . approaching bird. All of this is not possible with a single-barreled shotgun, only with a double-barreled one, no matter whether S×S or O/U.

Regulation [ edit ]

Regulation is a term used for multi-barreled firearms that indicates how close the barrels shoot to the same aiming point. A poorly regulated gun can consistently hit on one barrel but consistently miss on the other, rendering the gun nearly useless for anything that requires two shots. However, the short ranges and spread of the shot creates significant overlap, so a small error in regulation on a double is often too small to be noticed. In general, the shotguns are regulated to hit the aiming point at a specific distance, usually the maximum expected range, as this is the range at which a full choke is used and where accurate regulation is most important. Adjustment is typically more important on side-by-side shotguns than over-and-unders because the perceived recoil is different.

Single-action and double-action refer to how a gun’s mechanism works when the trigger is pulled. The “double” in double-action means that the trigger performs two functions: cocking and then firing the gun. The hammer cannot be manually cocked back; only pulling the trigger can do that. Most guns are single-action (SA), but some handguns (pistols and revolvers) can be double-action (DAO – aka double-action only) or single-action/double-action (SA/DA).

action

A mechanism is the trigger, hammer and safeties considered as one unit. A weapon’s action defines how the mechanism is constructed and used. The types of action (single/double) vary depending on the function of the trigger.

In a single action, pulling the trigger releases the hammer, firing the cartridge in the chamber. They are called “single action” because only one mechanism – the firing of the hammer – occurs when the trigger is pulled to allow the gun to fire. Single-action revolvers (SA) must be manually cocked before each shot. Single-action automatics like the 1911 Patter pistols must be manually cocked before the first shot, but on subsequent shots the hammer is cocked automatically by the rewarding motion of the recoiling slide.

Double action handguns come in a variety of forms. When the trigger is only pulled on a double action (DAO) and on handguns with firing pins, the hammer (or firing pin) is retracted (and on revolvers, the cylinder is rotated). Once the trigger has been pulled back to its “breaking point”, the hammer is released and dropped onto the cartridge, firing it. All shots are fired with the hammer initially decocked, as the hammer does not have an SA lock point.

On double-action/single-action (DA/SA) handguns, or “traditional double-action” pistols, the trigger is identical to a DAO revolver, but the recoil slide automatically cocks the hammer after the weapon is fired. With each subsequent shot, the trigger works as a single action. Both DA/SA pistols and DA revolvers with exposed hammers can fire SA whenever the shooter chooses.

pull trigger

A single-action revolver has an easy and smooth trigger because it only has to drop the hammer. This allows for more accurate shooting.

A double-action revolver has a heavier, longer trigger pull, which can adversely affect accuracy.

Reload

Reloading is pretty much identical for automatic pistols regardless of action type. Dropping an empty magazine, inserting a full magazine, inserting a rack, or dropping a slide.

A single-action revolver typically requires the user to open the gate at the rear of the barrel to insert each cartridge, then rotate the barrel to bring the next chamber into use.

A double-action revolver can be reloaded more quickly by swinging the cylinder out of the gun frame and then using a quick loader, or loading the cartridges by hand.

security

Some consider double-action guns to be safer than single-action guns, but modern innovations have made it very difficult to unintentionally discharge a well-maintained firearm of either type. Safety notches, firing pin blocks, hammer blocks, transfer bars, trigger separators, grip and trigger safety are good examples.

Don’t give up single action, double action pistols for CCW

Looking at the pistols that have been developed in recent years, one might get the impression that the single-action, double-action pistol is dying out. Why bother, some say, since the bolt-fired (technically a percussion pistol is more of a hammerless SA, but whatever) design is so much easier to use?

It so happens that there are many supporters of the SA/DA trigger format for various reasons. Not everyone is a fan of the Glock safety, or rather the full, full-full and full-full, built-in trigger safety of firing pin rifles that only have a built-in trigger safety.

The rise of SA/DA

Some of the terminology can be confusing, as some people use the terms single-action/double-action (or SA/DA for short) and double-action interchangeably, when a double-action-only pistol (or DAO) means something entirely different is.

SA/DA pistols can be fired in either state because pulling the trigger with the hammer down will cock the pistol by bringing the hammer backwards and dropping it, thereby unloading the firearm. Or, if the operator prefers, the hammer can be manually cocked and fired in single-action mode. Double-action triggers are longer and require more pressure than single-action triggers.

However, a double-action only weapon cannot be manually cocked. it’s a long deduction or nothing. Granted, this design is more common on revolvers than cars, but there are a good number of semi-automatic pistols in DAO configuration. Kahr, for example, does nothing else.

The first SA/DA pistols were revolvers, first appearing in the 1850s during the cap-and-ball era but apparently thriving from there. The first semi-automatic SA/DA pistols did not appear until the 1930s, but caught on because they are almost perfect for autoloading pistols. Unlike a revolver, which must be cocked in order to be placed in single-action mode, an SA/DA pistol is placed in SA mode after a cartridge has been discharged or manually cocked.

Thus, an SA/DA pistol can be carried with the hammer pointing downwards and a round chamber. Single action autos like the 1911 must be carried with the hammer back and safety or cocked before firing.

Why some people prefer single action/double action pistols

Why do single action/double action pistols persist, those relics of firearm design? There are a number of reasons.

One of the biggest reasons is actually security. Unlike a single-action pistol or a firing pin pistol, a single-action/double-action pistol can be loaded, hammer down, but carried decocked. It’s the goldilocks of concealed carry conditions in that regard. It requires twice as much trigger pull to fire as most firing pin fired guns (i.e. Glocks and clones) but without the need to cock the hammer like most single action guns. This allows the pistol to be drawn and fired without additional action, but is less prone to accidental discharges.

The range of SADA handguns

While the plastic percussion pistols are certainly widespread, there are still very many manufacturers of SADA handguns with a variety of different features and design variations.

The advantage of the design is of course its versatility. The operator can choose to activate the safety if so equipped or not, as he sees fit. Granted, not all SADA pistols actually have a manual safety; Some models are equipped with a decocking lever instead of a safety lever, allowing the pistol to be decocked for carrying in double-action mode.

However, if you want to wear it “cocked and locked”, this is possible with models with a manual safety device. In fact, manual safety levers on CZ pistols can only be activated when the hammer is cocked. Beretta (and some other manufacturers) offer a hybrid security that relaxes AND activates the security mechanism.

The long trigger is only a problem for one shot; After the first shot is fired, the slide cocks the hammer for each subsequent shot – making follow-up shots a breeze due to the smoother pull of the single-action trigger.

While more complex than a firing pin pistol, the SADA design is not likely to disappear from the market anytime soon, largely due to the versatility of its operation. That makes a good single double action pistol a good sidearm, which is why they have persisted and will continue to do so.
