The Sig Sauer P320-XFULL is a full-size 9mm striker-fired pistol built for shooters who want a duty-grade platform with genuine accuracy and control. It's the full-size entry in Sig's X series, designed for those balancing serious performance with practical carry capability. The 4.7-inch barrel and slide deliver the sight radius and velocity that matter for precision work, whether on the range or in the field, while the X Grip Module keeps recoil predictable and your hand position high and secure.
What sets the P320-XFULL apart is its thoughtful ergonomics: the extended beavertail, deep undercut trigger guard, and improved magwell are engineered to lock your grip in place and control muzzle rise. The modular design is a Sig hallmark—the fire control unit (FCU) handles the manual safety and X Flat Trigger, while the grip and slide swap freely, making this gun adapt to your needs or future upgrades. The optic-ready slide accepts the Romeo X or DeltaPoint Pro optics directly, and the XRay3 day/night sights ensure you can aim in any light. A mechanical loaded chamber indicator adds a layer of safety feedback.
This California-compliant model ships with two 10-round steel magazines and arrives ready to shoot. The stainless steel frame and slide (finished in Nitron for durability) pair with a carbon steel barrel, while the M1913 accessory rail opens the door to lights or lasers. At 29.6 ounces with a magazine, the P320-XFULL is substantial enough to manage recoil smoothly but lean enough that serious carry isn't out of the question for those who want a full-size gun.

Yes. The P320-XFULL ships with XRay3 day/night sights standard. These remain as a backup if you mount an optic, or serve as your primary aiming system if you prefer iron sights.
Yes. The modular P320 design means the fire control unit (FCU) is separate from the grip and slide. Over time, you can upgrade or swap the grip module or slide independently, though the FCU contains the safety and trigger and remains the core of the platform.
