SIG Sauer SIG P320 Full Size 9mm

The P320 Full Size is SIG Sauer's flagship modular striker-fired pistol, chambered in 9mm with a 17+1 capacity. The defining feature of the P320 platform is its serialized Fire Control Unit (FCU) — a self-contained internal chassis that constitutes the legal firearm. The FCU can be dropped into different grip modules, slides, and barrel assemblies to reconfigure the pistol's size, caliber, and ergonomics without purchasing a new firearm. The P320 won the US Army Modular Handgun System competition in 2017, selected over Glock, Beretta, and others to replace the M9.
