This guide explains the internal mechanics of double-action (DA) and double-action-only (DAO) revolver triggers, contrasting them with single-action (SA) triggers. It details how pulling the trigger in DA mode cocks and releases the hammer using the hammer strut, and how DAO revolvers omit the SA capability. The explanation highlights the simplicity and reliability of revolver mechanisms.

This video demonstrates how to significantly reduce the heavy trigger pull on a Remington Rolling Block Model 1871 Army Pistol. By carefully stoning the sear notch to alter its angle and then re-hardening the part, the trigger pull can be reduced from a prohibitive 16.25 pounds to a manageable 3 pounds. This modification greatly improves control and accuracy for shooting historical firearms.
