A revolver is a pistol with a revolving cylinder containing six chambers. Each chamber can hold a metal cartridge, and when one cartridge is shot, the cylinder automatically rotates (no extra hand or action required), readying the next chamber for firing. A revolver uses metal cartridges as ammunition.
