The Sig Sauer P320 X-Full 9mm Nitron 17+1 Romeo-X pairs the proven P320 X-Series platform with a factory-mounted Romeo-X Sig-Loc Pro optic for fast, intuitive aiming. Built around a modular polymer X grip frame and a 4.7" barrel, this striker-fired semi-auto pistol delivers a familiar P320 feel with enhanced sighting and modern ergonomics.

This X-Full configuration offers a generous 17+1 capacity with two 17-round steel magazines, an M1913 accessory rail for lights or lasers, and XRay3 Day/Night sights that co-witness with the optic. Its straight X-Series trigger promotes a consistent, clean break, while the 8" overall length and 30 oz weight make it well suited for home protection, duty use, and extended range sessions. Backed by Sig Sauer’s reputation for innovation and quality, the P320 X-Full Romeo-X is designed for shooters who value reliability and refined handling.
