The SIG Sauer P320 Full 9mm is the duty-grade, full-size modular platform that has become the standard-issue sidearm for federal, state, and local law enforcement agencies nationwide. Designed for operators who demand reliability in high-stress environments, this 18-round pistol delivers the capacity, ergonomics, and accuracy required for professional defensive and tactical applications. Whether you're outfitting a duty belt, building a duty-grade personal defense platform, or seeking a proven full-size 9mm for home or vehicle defense, the P320 Full represents SIG's commitment to modular engineering and consistent performance.
Built on SIG's modular Locking System (MLS) architecture, the P320 Full separates the fire control group from the serialized lower assembly—allowing seamless caliber and size conversions with minimal parts swaps. The full-size frame provides a 4.7-inch barrel platform that optimizes sight radius and muzzle velocity for 9mm Luger ammunition, while the 18-round capacity balances firepower with manageable recoil impulse. Internally, the P320 employs a striker-fired, short-reset trigger mechanism and passive firing pin safety, delivering consistent single-action performance and reliable function across thousands of duty and training cycles. The stainless steel slide and hardened steel components are engineered for corrosion resistance and longevity in demanding field conditions.
This full-size configuration suits duty carry, home defense, and dedicated range training for shooters and professionals transitioning from mid-size to larger frames. The 8-inch overall length and modular design make it compatible with a vast ecosystem of holsters, light mounts, and optic adapters—enabling rapid customization for mission-specific requirements. The P320 Full accepts standard P320 magazines, ensuring logistical simplicity across multi-platform armories and personal arsenals.
