What does single action and double action mean?

4 min read

Asked by: Brittany Bilann

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

What is better double action or single?

A single action revolver has a light and smooth trigger pull, as it only needs to drop the hammer. This allows for more accurate shooting. A double action revolver has a heavier, longer trigger pull, which can be detrimental to accuracy.

Is Glock single or double action?


The Glock 19 has an overall length of 7.36 inches and a barrel length of 4.01 inches. It is a double-action pistol, meaning that after a round is chambered the pistol only requires pulling the trigger to set the firing pin and fire. Subsequent shots will also only require a single trigger pull.

What does double action mean on a gun?

Double-Action (DA)

Double-action firearms have a longer, stiffer trigger pull than a single-action gun because you’re doing the extra work of cocking the hammer with the trigger.

Why use a double action pistol?

Double Action Only (DAO)

Some revolvers like the Smith & Wesson Model 642 however, are Double Action Only, where pulling the trigger will fire a round every time. This reliable setup allows the shooter to safely operate the firearm without the need of the slightly outdated, light single action trigger pull.

Can you fan a single action revolver?

One of the fastest and slickest looking techniques to fire a revolver has been made extremely popular due to its common depiction in westerns. That technique is called “fanning.” This action is done by holding down the trigger on a single action revolver, and then rapidly pulling back the hammer.

Is hammer or striker fired better?

The best benefit of the striker-fired pistol is its ease of operation. They are easier to deploy since they do not have protruding components like a hammer that can hang up on clothing. Additionally, most striker-fired pistols do not have an external safety to disengage before firing.

Why do Glocks have 2 triggers?

The Two Triggers Serve as a Safety Purpose

The biggest reason why Glock pistols have two triggers is that this serves as a safety mechanism. Even though the safety mechanisms of Glocks can vary slightly from handgun to handgun, most Glocks do not use the same safety features as traditional handguns.

Will a Glock fire if dropped?

Glock calls the striker-fired system its “Safe Action” operating system, and there is a lot of truth to that. A Glock can only be fired if the trigger is depressed, meaning accidental falls from holsters and other objects to the ground cannot, for example, cause a hammer to fly forward and impact the primer.

Is a 1911 single or double-action?


The 1911 is a single-action, semi-automatic, magazine-fed, recoil-operated pistol chambered for the . 45 ACP cartridge. This operating system became the most popular of nearly all the modern centerfire pistols adopted during the 20th century.

Is a Glock 19 single or double-action?

Safety action and the Glock safety action is a little different it's not a single action and it's not really a double action. It is a Glock action and the way it works I've got what I'm torn down here

Can a gun shoot without pulling the trigger?

It is important to realize that just because a firearm goes off, doesn’t always mean someone pulled the trigger. Poorly designed rifles, shotguns, and handguns can fire a round even when the trigger has not been pulled. The most common unintended discharges occur when the firearm is bumped or the safety is moved.

Are there double-action only pistols?

A double-action-only (DAO) pistol is a firearm in which the mechanism restricts the trigger to performing both actions — cocking and releasing the striker or hammer. In contrast to double-action/single-action (DA/SA) pistols, the slide does not recock the hammer during the firing cycle.

Is double-action the same as semi-automatic?

“Double-action” refers to the action of the gun or, more specifically, what happens when the trigger is pulled. “Semi-automatic,” on the other hand, refers to what happens when the gun engages in its cycle of fire — the operation of the gun as a whole, not just the trigger.

Are striker fired handguns double-action?

Double-action/single-action means the first shot out of the gun is fired by cocking and releasing the firing mechanism — hammer or striker — with the first trigger pull.
