SIG P320 Full Size

The SIG P320 revolutionized the handgun market with its modular fire control unit (FCU) design - the serialized component that can be swapped between different grip modules, slides, and calibers. Winner of the US Army's Modular Handgun System (MHS) contract as the M17/M18, the P320 has proven itself in military and law enforcement service worldwide. The full-size variant provides the largest grip and longest sight radius in the P320 family, making it ideal for duty use, home defense, and competition.

The striker-fired action delivers a consistent trigger pull around 6 pounds with a clean break and tactile reset. The modular design means you can legally purchase additional grip modules and slides without going through an FFL - only the FCU is the firearm. This makes the P320 the ultimate platform for shooters who want one gun that can be configured multiple ways. The full-size model accepts standard P320 magazines up to 21 rounds.

SIG's continuous improvement of the P320 has addressed early concerns and created one of the most refined striker-fired pistols on the market. The current production models feature improved triggers, enhanced drop safety, and refined ergonomics. The P320's combination of modularity, proven military service, and extensive aftermarket support makes it a top choice for serious shooters.
