A Modern Stocked Pistol: B&T's Universal Service Weapon (USW)
This guide details the installation of the B&T USW chassis system, transforming standard pistols like the Glock 17/19 and Sig P320 into stocked carbine-like platforms. It emphasizes safety during disassembly and reassembly, the integration of the fire control unit, and the mounting of optics. The B&T USW concept, pioneered by Karl Brügger, aims to enhance handgun accuracy under stress for law enforcement applications.
