Sig Sauer P320 320F9Bssp10 9Mm 4.7 Or 10R Blk$504.00
Availability: In Stock
The Sig Sauer P320 in 9mm is a full-size duty and defensive pistol built on a modular platform that balances capacity, shootability, and versatility. This particular configuration pairs a 4.7-inch carbon steel barrel with a medium full-size grip module, delivering the handling characteristics serious shooters expect from a professional-grade service pistol. The optic-ready slide accepts Sig's PRO optic mounting footprint, so you can add a red dot without gunsmithing—a practical upgrade path for duty, competition, or defensive use. Whether you're equipping a duty belt, building a defensive rig, or running the gun at the range, the modular P320 design lets you tailor it to your needs.
Ergonomics matter in a full-size duty gun, and the P320's medium grip module is sculpted to fit a wide range of hand sizes while the full-length accessory rail accommodates lights, lasers, or other attachments. The trigger is a crisp, predictable striker-fired design—no safety lever to manage under stress. SIGLite night sights front and rear come standard, so you're ready to shoot in low light right out of the box. Two 17-round magazines give you solid baseline capacity for defensive or duty applications.
The slide and frame are stainless steel with Sig's Nitron finish on the slide, a tough DLC coating on the barrel—both proven to stand up to hard use, cleaning, and corrosive environments. At 28.3 ounces loaded and 8 inches overall length, it's a full-size duty gun with the heft and pointability you'd expect. The 6.5-inch sight radius supports both iron sight and optic-mounted accuracy out to typical defensive ranges and beyond.

Yes. The full-size medium grip module, 17-round capacity, night sights, and accessory rail are standard features for duty and defensive use. The 4.7-inch barrel balances accuracy and handling for those roles.
