ABSTRACT:
A spring-loaded safety button is mounted in an opening in the forward end of a gun stock so that it will naturally fall beneath and be depressed by, the thumb on the trigger hand of the person firing the gun. In one embodiment the button registers with the rear end of a pivotal lever, the forward end of which has thereon a hook which normally engages the rim of the firing pin to prevent the gun from being fired until the button is depressed to swing the lever in a direction to disengage the hook from the firing pin. In a second embodiment the button has a shank which extends slidably downwardly behind the trigger of the gun. A projection on the shank normally engages the rear of the trigger to prevent it from being operated, but when the button is depressed the projection registers with a notch in the back of the trigger to allow the latter to be pivoted to fire the gun.
