ABSTRACT:
An improved magazine gun lock safety for a semiautomatic handgun has a rectangular safety catch with a right angled OFF activating lever affixed on one side. When the magazine is removed from the gun magazine chamber, the safety catch which is pivotal angles over pushed by a biasing spring so the OFF lever protrudes through an opening into the empty magazine chamber. In this position, the safety is ON and interferers with the hammer spring guide. The gun hammer spring can not activate the trigger-hammer mechanism and the hammer is immobilized preventing the gun from being fired. If a live cartridge has remained undetected in the firing chamber, the gun cannot be fired accidentally. When the magazine is pushed back into the handgun magazine chamber, it forces the OFF activating lever back out of the handgun magazine chamber and the safety catch is in the OFF position releasing the hammer spring guide. The trigger-hammer mechanism is then operational and the gun can be fired.
