Semi-auto pistols, like Glocks, can feel like single-action firearms because of their light, short-travel triggers. ![]() This process puts the firing pin under spring tension, and when the trigger is pulled, releases the tension, which jerks the firing pin forward and ignites the cartridge’s primer in the chamber. The typical sequence involves pulling the slide back and letting its forward return, loading the first round. With striker-fired pistols, there is no hammer.

Depending on the size and caliber of the pistol, these magazines may hold multiple bullets, giving you more rounds on tap before you need to reload your pistol as compared to a revolver, for example.Įxamples of a firing mechanism are a single-action trigger, double-action trigger, double-action-only trigger (DAO), double-action/single-action trigger, and striker-fired, which we detail below.
