ABSTRACT:
A safety for hammer-equipped pistols, which includes a lock pin slidably mounted in the handle of a pistol, a companion lock pin spring biasing the lock pin inwardly of the handle toward the hammer, a locking rod slidably mounted in the handle in angular relationship with respect to the lock pin, the upper end of which locking rod is adapted to normally engage a seat provided in the lock pin and a release pin normally located in a release pin seat provided in the base of the handle, for engaging the opposite, or lower end of the locking rod and preventing relative movement between the locking rod and the lock pin. In a preferred embodiment, one end of a release pin cable is attached to the release pin and the opposite end of the cable is secured to the pistol holder, wherein seizure and extension of the pistol beyond the length of the cable pulls the release pin from the release pin seat and allows the locking rod to slide downwardly inside the pistol handle and facilitate forward projection of the lock pin responsive of the lock pin spring and locking of the hammer to prevent firing of the pistol.
