In firearms terminology, an action is the mechanism of a breech-loading weapon that handles the ammunition or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all are single-shot weapons with a closed off breech. Instead, the ignition mechanism is referred to
A semi-automatic pistol is a type of pistol that is semi-automatic, meaning it uses the energy of the fired cartridge to cycle the action of the firearm and advance the next available cartridge into position for firing. One cartridge is fired each time the trigger of a semi-automatic pistol is pulled; the pistol's "disconnector" ensures this behavior.

A bolt is the part of a repeating, breech-loading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The extractor and firing pin are often integral parts of the bolt.
Locked breech is the design of a breech-reloading firearm's action. This is important in understanding how a self-reloading firearm works. In the simplest terms, the locked breech is one way to slow down the opening of the breech of a self-reloading firearm when fired. The source of power for the movement is recoil.
Limp wristing is a phenomenon commonly encountered by semi-automatic pistol shooters, where the shooter's grip is not firm enough and the wrist is not held firm/straight enough to keep the frame of the firearm from traveling rearward while the bolt or slide of the pistol cycles. This condition often results in a failure to complete the operating cycle, properly termed a malfunction, but commonly termed a "jam". Rifles and shotguns, if fired without the stock in the shoulder, may also be prone to limp wristing. Of the important variables involved in this type of malfunction, bullet and gas momentum, slide and barrel mass, recoil spring pre-load and spring rate, and shooting hand and arm mass are much more important than the compliance (limpness) of the wrist.
