In addition to its primary role as a safety device, the Safety Lever serves as the resting place for your thumb. With a proper grip, your thumb presses against the Safety Lever and provides much of the leverage necessary to control the gun under recoil. If the safety doesn’t mate with your thumb properly, or has sharp edges, it makes the gun difficult to control and painful to shoot. Bill’s Custom Automatics takes great care to de-edge and re-shape the safety into a comfortable platform that won’t gouge or bite your thumb. This small detail is essential to making a world class 1911 that can be shot like a champion.
