This guide explains the fundamental differences between single-action (SA) and double-action (DA) trigger systems, as demonstrated by 1st Shot Tactical. It covers how the hammer and trigger interact in each mode, leading to distinct trigger pull weights. Understanding these mechanics is crucial for safe and effective firearm operation.

Quick Summary

Single-action triggers require the hammer to be pre-cocked, with the trigger solely releasing it for a light pull. Double-action triggers combine cocking and releasing the hammer in one pull, resulting in a heavier trigger weight. This difference impacts firearm handling, safety, and shooting precision.

Frequently Asked Questions

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

In single action, the hammer is already cocked, and the trigger only releases it, resulting in a light pull. In double action, the trigger pull must first cock the hammer and then release it, making the pull much heavier.

How does the trigger pull weight differ between single and double action?

Single-action trigger pulls are significantly lighter, often around 4-5 lbs, designed for precision. Double-action pulls are much heavier, typically 10-14 lbs or more, providing an added safety margin.

What firearm is shown demonstrating single vs. double action?

The video features the Arex Rex Zero 1 Tactical pistol, which is a DA/SA (Double Action/Single Action) firearm, allowing for both types of trigger operation.

Why is understanding DA/SA important for firearm owners?

Understanding DA/SA mechanics helps anticipate trigger feel and weight, crucial for safe handling, accurate shooting, and effective use in various scenarios, from training to self-defense.
