The SIG Sauer P320 X-Full is a 9mm Luger full-size striker-fired pistol that ships here with a SIG ROMEO-X Pro red dot factory-installed, mated to front and rear X-Ray3 day/night sights for a co-witnessed backup sight picture (brand part no. 320XF-9-BXR3-RXSL). SIG Sauer builds the X-Full on a stainless-steel frame with an integrated beavertail and Picatinny accessory rail, and the 4.7-inch barrel and 17-round magazines give it genuine duty-size capacity and sight radius. The X-Series grip module improves recoil management over a standard P320 grip module, and at roughly 1.82 lbs it carries the heft of a full-size duty pistol without feeling unwieldy. It ships with two 17-round magazines and is built for range, duty, or home-defense use where capacity and a ready-to-go optic both matter.
