Abstract
Abstract An expendable handgun with a handle hingedly mounted on the rear portion thereof. A detent mechanism is included which locks the handle in either a safety position or a firing position. The detent mechanism has detent pins which are in force transmission relationship with a firing pin spring and which compress the spring when the handle is forced into a firing position which compression results from the action of cam surfaces formed on the upper portion of the handle moving the detent pins forward. In the the safety position, the handle covers an included triggering mechanism and causes the detent mechanism to decompress the firing pin spring so as to ''''disarm'''' the handgun.
