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.
