A revolver is a repeating handgun that has a revolving cylinder containing multiple chambers and at least one barrel for firing. The revolver allows the user to fire multiple rounds without reloading after every shot, unlike older single-shot firearms. After a round is fired the hammer is cocked and the next chamber in the cylinder is aligned with the barrel by the shooter either manually pulling the hammer back (single action operation) or by rearward movement of the trigger (double-action operation).
Revolvers still remain popular as backup and off-duty handguns among American law enforcement officers and security guards and are still common in the American private sector as defensive and sporting/hunting firearms. Famous revolvers models include the Colt 1851 Navy Revolver, the Webley, the Colt Single Action Army, the Colt Official Police, Smith & Wesson Model 10, the Smith & Wesson Model 29 of Dirty Harry fame, the Nagant M1895, and the Colt Python.
Though the majority of weapons using a revolver mechanism are handguns, other firearms may also have a revolver action. These include some models of grenade launchers, shotguns, rifles, and cannons. Revolver weapons differ from Gatling-style rotary weapons in that in a revolver only the chambers rotate, while in a rotary weapon there are multiple full firearm actions with their own barrels that rotate around a common ammunition feed.
