Revolver

Revolvers were the first truly multi shot firearms. Previously a gun that could be quickly fired more than once used multiple barrels and firing mechanisms, which basically equates to welding guns together. A revolver works by having several firing chambers arranged in a circle in a cylindrical block which are brought into alignment with the firing mechanism and barrel one at a time. A single action revolver requires the hammer to be pulled back by hand before each shot. In a double action revolver, the trigger pull can pull back the hammer as well as release it.

Most commonly such guns have a six shot capacity and each chamber has to be reloaded manually. This makes the procedure of reloading such a weapon slow (even with the help of such devices as quick loaders). On the other hand due to the simplicity of design and relatively few moving parts, a revolver is cheap to make and almost guaranteed to work, first time, every time. For these reasons, such guns are the most commonly owned weapons for personal self defence.
