This video explains the fundamental differences between single-action (SA) and double-action (DA) trigger mechanisms in firearms. It details how SA requires a pre-cocked hammer for a lighter pull, while DA cocks and releases the hammer with a single trigger pull, resulting in a heavier, longer stroke. The video also highlights the utility of decocking levers on modern DA/SA pistols for safe transitions.

Quick Summary

Single-action (SA) triggers require a pre-cocked hammer and offer a lighter, shorter pull. Double-action (DA) triggers perform two functions: cocking the hammer and releasing it with a single, heavier, longer pull. Modern DA/SA pistols often use decockers to safely transition between modes.

Frequently Asked Questions

What is the main difference between single-action and double-action triggers?

In single-action (SA), the hammer is pre-cocked, and the trigger only releases it. In double-action (DA), the trigger performs two tasks: cocking the hammer and then releasing it, resulting in a heavier pull.

How does a decocker lever work on a DA/SA pistol?

A decocker lever allows the user to safely lower the hammer from a cocked (SA) position back to the double-action position without firing the pistol, even with a round in the chamber.

Why is the single-action trigger pull lighter?

The single-action trigger pull is lighter because the hammer is already cocked. The trigger only needs to overcome the sear's resistance to release the hammer, requiring less force and travel.
