The P320 X-Full combines the X-Series flat trigger, XRay3 sights, and optics-ready slide with the full-size grip module and 21-round magazines. It sits between the standard Full Size and the X-Five in the lineup — sharing the X-Series ergonomic improvements without the competition-specific weight and 5-inch barrel of the X-Five. A duty and carry option for shooters who want X-Series quality in a standard service pistol format.
