What is a double action trigger?

Martin Mapa Answered question September 7, 2022

A double action trigger is a mechanism used in firearms that allows the user to cock and fire the gun in one motion. This type of trigger is typically found on semi-automatic pistols and revolvers.

Double action triggers can be used for self-defense or target shooting.

When used for self-defense, the double action trigger allows the user to keep their finger off the trigger until they are ready to shoot. This can help prevent the unintentional discharge of the firearm.

Target shooters often prefer double action triggers because they allow for a more consistent trigger pull, which can improve accuracy.


It’s a type of firearm trigger that performs two actions, such as releasing the hammer and firing the gun. It contrasts with a single action trigger, which performs only one action, such as releasing the hammer.

Double action triggers are usually found on revolvers and semi-automatic pistols. They are designed to provide a more consistent pull weight than single action triggers, which can make them easier to shoot accurately. However, they also tend to be more difficult to pull, which can make them more challenging for new shooters to operate.

A double action trigger is a type of trigger that can be pulled both single-action and double-action.

A double action trigger requires more force to pull than a single action trigger, but it also results in a shorter distance between the firing pin and the primer.

As a result, it’s less likely for the firing pin to bounce off the primer and miss its mark.

It’s a type of firearm trigger that performs two functions – one to cock the hammer and another to release the firing pin.

This design was first used in 1878 by Johannes Braendlin on his rifle called the Dreyse Needle Gun. Double action revolvers were popularized in the early 20th century, and are still in use today.
