Colion Noir provides an expert breakdown of different pistol action types, demystifying the differences between striker-fired, single-action only, double-action/single-action, and hybrid internal hammer systems. He uses specific FN pistol models to illustrate each mechanism, emphasizing that action type dictates the firing mechanism, not necessarily performance characteristics like recoil or deadliness. This guide is essential for understanding fundamental firearm operation.

Quick Summary

Colion Noir explains that pistol action types (striker-fired, single-action, double-action) dictate the firing mechanism, not recoil or deadliness. Striker-fired offers consistency, SAO provides performance, and DA/SA offers versatility. Understanding these differences is key to firearm operation and selection.

Frequently Asked Questions

What is the main difference between striker-fired and hammer-fired pistols?

Striker-fired pistols use a spring-loaded firing pin (striker) that directly ignites the primer, offering simplicity and consistent trigger pulls. Hammer-fired pistols use an external or internal hammer that must be cocked before the trigger releases it, offering varied trigger characteristics like SAO or DA/SA.

How does a single-action-only (SAO) pistol work?

In a single-action-only pistol, the trigger performs only one function: releasing the hammer or striker. The hammer/striker must be manually cocked by racking the slide before each shot, resulting in a crisp, light trigger pull.

What is a double-action/single-action (DA/SA) pistol?

A DA/SA pistol allows the trigger to perform two functions. The first pull is long and heavy (double-action), cocking and releasing the hammer. Subsequent pulls are short and light (single-action) because the hammer is already cocked.

Does the action type of a pistol affect its recoil or deadliness?

No, the action type primarily refers to the internal mechanism used to fire the gun. Factors like caliber, ammunition, barrel length, and shooter technique have a much greater impact on recoil and a firearm's effectiveness.
