This is a Wilson Combat Safety known as the Bullet Proof, model 298BBP.
The Bullet Proof 1911 beavertail safety is machined from hardened bar stock steel without the flaws or inclusions that can plague many mass produced cast or molded inferior 1911 parts. The exclusive Wilson compound joint radius is easy to fit by hand and the modified grip safety arm allows easy disassembly. A pocketed rear tang for a recessed commander hammer and a raised rear tab for positive safety release will make this your preferred part for high end custom builds.
