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.
