This jig is designed for the straightforward installation of our beavertail grip safety. The heat-treated tool inserts into the frame via the thumb safety hole, enabling precise 0.25 inches radius cuts on each side of the frame on the initial attempt, even when using basic hand tools. The buttons are designed to screw together, securing themselves to the firearm for effortless installation. It is ideal for both gauging and fine finishing, offering significant value as a reusable professional tool.
