The P320 pistol is produced by US-based branch of international SIG-Sauer company for civilian, military and law enforcement use. First introduced in 2014, it is now available in four different sizes, each having three grip frame sizes (S, M and L) and ranging from full-size model (intended for duty use or dynamic shooting sports) to compact and sub-compact models, intended for concealed carry for self-defense. It’s a modular, multi-caliber system that is built around single unified steel frame that hosts trigger system and slide rails. This serially numbered steel frame is inserted into the polymer grip frame (receiver), and appropriate barrel, slide and magazine(s) are added to complete the desired configuration of the gun.
The SIG-Sauer P320 modular pistol is short recoil operated, locked breech handgun that uses Browning-type locking system with cam-operated vertically tilting barrel. It’s a striker-fired weapon, with pre-tensioned striker spring and no manual safeties. Automated trigger safety is optional for all models. Gun is designed to be as “fool-proof” during maintenance as possible, requiring no tools and no trigger manipulations during disassembly and reassembly.
