Revolver

A Revolver is a type of repeating firearm that uses a rotary cylinder to store ammunition. There are two types of revolvers: single-action, where the hammer must be pulled back manually after every shot, and double-action where each trigger pull pulls back the hammer and cycles the cylinder.
