Abstract
A multi-shot handgun includes a handgun body, a cylinder mounted on the handgun body for indexing, and a hammer mounted on the handgun for pivoting displacement between a retracted and a firing position. An electric motor is energized from a battery upon actuation of a switch and has an output shaft on which two pinions are mounted for shared rotation, one meshing with a gear which indexes the cylinder, and the other meshing with a gear wheel segment which is a part of the hammer. The other pinion is circumferentially incomplete and has a flat portion which permits unimpeded displacement of the gear wheel segment and thus of the hammer toward its firing position toward which it is biased by a spring. Upon closing of the switch, the electric motor simultaneously indexes the cylinder and displaces the hammer towards its retracted position so that, when the hammer is released for displacement toward the firing position, it impacts that cartridge which is indexed into the position of alignment with the path of displacement of the hammer so that the propellant charge of the cartridge is ignited.
