Automatic revolver : ウィキペディア英語版 | Automatic revolver
An automatic revolver (more correctly, a semi-automatic revolver) is a revolver that uses the energy of firing for cocking the hammer and revolving the cylinder, rather than using manual operations to perform these actions. Examples of genuine semi-automatic revolvers are rare, and the term is more often applied to break-open revolvers with automatic systems for ejecting spent casings on opening. == Description == A standard revolver is a manually operated weapon, using the action of cocking the hammer to advance the cylinder in a single-action, or the action of pulling the trigger to advance the cylinder and cock the hammer in a double-action. The idea behind an automatic revolver is to automate both actions, removing the need to manually cock the hammer between shots while retaining the lighter trigger pull of the single-action. This is accomplished by use of a reciprocating slide on the upper part of the frame, the motion of which is used to rotate the cylinder and cock the hammer in much the same way as is used in the majority of semi-automatic pistol designs.
