This video details the assembly of a custom SIG USW-320, a modular pistol build. It highlights the SIG P320's modularity, where the Fire Control Unit (FCU) is the serialized part. The build incorporates a B&T USW chassis, an Agency Arms slide with a compensator, and a Trijicon RMR optic. Crucially, it notes that adding a folding stock to the USW-320 requires NFA registration as a Short Barreled Rifle (SBR).

This review explores the B&T USW (Universal Service Weapon) concept, starting with the original USW-A1 based on the Sphinx pistol and its history dating back to WWI PDW concepts. It highlights the evolution to modern chassis systems, including the USW-320 for the Sig P320 and a new aluminum chassis for Glock 17 (Gen 3-5). The chassis systems offer a stocked, holsterable PDW solution, enhancing accuracy while maintaining compact size.
