ABSTRACT:
A safety mechanism to prevent the accidental discharge of a firearm such as an automatic pistol when the firearm impacts on a hard surface utilizes a second spring loaded slide bolt as an impact safety in addition to a conventional, trigger-activated spring biased slide bolt. The second safety bolt and its bias spring are structured and located so that an impact which causes the trigger-activated safety bolt to move out of its normal "safety-on" position also causes the second slide to move against its bias spring to engage a recess on a firing pin and thereby prevent the weapon from firing. Also, when the firing pin is located in a slide of an automatic pistol, the slide, firing pin and hammer are structured so that a movement of the slide on impact towards the hammer causes the rear edge of the slide to strike the hammer with the firing pin spaced from the hammer.
