Single Action VS Double Action Revolver - What's the Difference??

This video explains the fundamental differences between single-action and double-action revolvers, focusing on their trigger and hammer mechanisms. It demonstrates that single-action revolvers require manual cocking of the hammer for each shot, while double-action revolvers allow firing by either manually cocking the hammer or by pulling the trigger, which also cocks and releases the hammer. The instructor emphasizes the heavier trigger pull in double-action mode when not manually cocked and recommends cocking the hammer for a lighter, more accurate first shot.

Quick Summary

The key difference between single-action and double-action revolvers is the hammer and trigger mechanism. Single-action requires manual hammer cocking for each shot. Double-action allows firing by pulling the trigger, which cocks and releases the hammer, or by manually cocking the hammer for a lighter pull. The double-action trigger pull is heavier when not manually cocked.

Frequently Asked Questions

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

The primary difference lies in how the hammer is cocked and the trigger is pulled. A single-action revolver requires the hammer to be manually cocked for each shot. A double-action revolver allows the hammer to be cocked and released by pulling the trigger, or it can be manually cocked for a lighter pull.

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

In a single-action revolver, the trigger pull is generally light and crisp after the hammer is cocked. In a double-action revolver, pulling the trigger without cocking the hammer results in a much heavier pull, as the trigger performs multiple functions. Cocking the hammer manually on a double-action revolver provides a lighter pull, similar to a single-action.

Can you fire a double-action revolver like a single-action?

Yes, you can fire a double-action revolver like a single-action by manually cocking the hammer before pulling the trigger. This method provides a lighter and often more precise trigger pull, which can be beneficial for accuracy, especially on the first shot.

Why is the trigger pull heavier on a double-action revolver when not cocked?

When the hammer is forward on a double-action revolver, pulling the trigger initiates a sequence: it rotates the cylinder to the next chamber, cocks the hammer, and then releases it to fire. This multi-step mechanical process requires more force, resulting in a heavier trigger pull compared to a manually cocked hammer.
