All About Handgun Actions: Double Action Revolver

Roy Huntington, editor of American Handgunner, explains the fundamental differences between double-action and single-action handgun mechanisms, focusing on revolvers. He clarifies that a double-action trigger performs two functions: cocking the hammer and firing the gun. In contrast, a single-action trigger performs only one function: firing the gun, requiring the hammer to be manually cocked beforehand. This explanation aims to demystify common firearm terminology for new enthusiasts.

Quick Summary

A double-action handgun mechanism means pulling the trigger cocks the hammer and fires the gun. A single-action mechanism means the trigger only fires the gun, requiring the hammer to be manually cocked first. This distinction is fundamental for understanding firearm operation.

Frequently Asked Questions

What is the difference between a double-action and single-action handgun?

In a double-action handgun, pulling the trigger performs two functions: it cocks the hammer and then fires the gun. In a single-action handgun, the trigger pull only performs one function: firing the gun. The hammer must be manually cocked before the trigger can be pulled.

How does a double-action revolver work?

A double-action revolver works by having the trigger pull accomplish two tasks. First, it rotates and cocks the hammer. Second, upon reaching a certain point in the trigger pull, it releases the hammer to fire the chambered round.

What does it mean for a handgun to be single-action only?

A single-action only handgun means that the trigger's sole function is to release the hammer and fire the gun. The hammer must be manually cocked by the shooter before each shot. This is distinct from double-action or combination actions.
