The XSeries XFULL configuration delivers a full-size duty-length slide with front and rear serrations and a removable rear-sight/cover plate over the optics cut. The Medium XSeries grip module adds an extended beavertail, an undercut trigger guard, and a SIG medallion, offering a secure, comfortable hold.
Its optics-ready PRO interface provides a direct-mount solution for compatible red dots when the cover plate is removed. Steel 3-dot sights are installed from the factory, with a high-visibility green front dot and a two-dot rear notch for fast alignment and a 6.6 in sight radius.
The striker-fired, short-recoil, locked-breech system pairs with a flat-faced trigger and a 3-point takedown that does not require a trigger press. Ambidextrous slide catch levers and a full-length dust cover with a 4-slot Picatinny/1913 rail add flexibility for setup and operation.
Key dimensions include a 4.7 in barrel, 8.2 in overall length, 5.5 in height, 1.3 in width, and an approximate weight of 29.5 oz. Capacity is 17+1 in 9mm Luger with a 1:10 twist barrel. Markings include “SIG SAUER P320” on the slide, “9mm x 19” on the barrel hood, and “NEWINGTON, NH, USA” on the frame.
