The SIG P320 XFULL 9mm with a 4.7" barrel and ROMEO red dot-ready slide brings the P320 series modular design into a competition and duty-ready package, combining a striker-fired fire control with a full-size, polymer frame that balances a 29.4 oz carry weight and a 17-round capacity for extended range sessions or serious defensive use. Youll notice the Shield/RMSC optic footprint cut into the black slide for fast target acquisition with a ROMEO-style red dot while the factory night sights provide a reliable backup sighting system in low-light scenarios; the semi-auto action is smooth and predictable for follow-up shots whether youre training high-round-count drills, working a competition course of fire, or issuing it to a duty holster. The XFULL designation signals the extended grip and slide length compared to compact P320 variants, offering improved sight radius and recoil control for shooters who want a controllable 9mm with modular grip options. Built with durable colored finish on polymer frame and slide detailing, this Sig Sauer pistol requires transfer via an FFL and is intended for owners who value versatility, optics integration, and a proven P320 platform.
