Abstract: A self-engaging safety is disclosed which works in addition to the standard grip safety having a forward edge slot and thumb safety of an automatic handgun having a frame, slide, mainspring housing, hammer and sear. The self-engaging safety has an elongated pin with an upper and lower end and a cross pin attached to the pin near its lower end at a right angle. The safety allows the grip safety and thumb safety to be deactivated only in a specific sequence. That sequence is that first the pistol handgrip must be gripped thereby deactivating the grip safety whereafter the thumb safety may be released allowing the gun to fire when the trigger is pulled. The self-engaging safety prevents the thumb safety from being deactivated prior to the grip safety being depressed.

Abstract: A manually actuated safety mechanism for a hand gun particularly of the type incorporating a rebound slide which is activated by a small hinged pin mounted on the trigger assembly to force the rebound slide back. The rebound slide has a small indentation in front to receive the pin, to in turn posiiton an internal safety or firing pin block accompanying the gun structure when manufactured, thereby blocking the hammer from engaging the firing pin. The safety mechanism is mounted within the handle of the hand gun and includes minimal moving parts and is disposable and configured to prevent travel of the rebound slide from a blocking position to a release position thereby preventing cocking of the hammer to accomplish proper positioning of the hammer, trigger assembly and firing pin block for the next firing cycle.
