Sig Sauer P320 Full Size 9mm Luger 4.7 inch 17+1 Nitron Slide Stainless Frame Polymer Grip

The Sig Sauer P320 Full Size 9mm marries duty-grade ergonomics with a modular striker-fired design that has become a benchmark in service pistols, and the 320F9B configuration brings a 4.70" black carbon steel barrel, serrated black Nitron stainless slide and a black stainless steel frame with integral Picatinny rail to shooters who want a robust, controllable 17+1 platform. With a 29.5 oz weight and full-size grip, the polymer/stainless construction soaks up recoil for fast follow-up shots while the steel 3-dot contrast sights and serrated slide improve sight acquisition and manipulations at the range, in competition, or on duty; the striker-fire action delivers a consistent trigger pull without an external manual safety, and the 4.7" barrel and 9mm Luger chambering balance accuracy and shootability for self-defense, duty, and practical target work. The P320 family is known for its modular fire control unit that allows serial-numbered interchangeability across frames and slides, and the Picatinny rail accepts lights and lasers for low-light applications, making this Sig Sauer Full Size P320 a versatile choice for operators, instructors, and serious recreational shooters.
