The X-Series XFULL configuration delivers a full-size grip module with an extended beavertail and high undercut for a secure, high-hand purchase. The flat-faced trigger provides a consistent, straight press. Controls include an ambidextrous slide catch and a reversible magazine release for flexible setup.
The 4.7 in carbon steel barrel is non-threaded and pairs with a black Nitron slide that has both front and rear serrations. The slide is cut for optics and uses a removable rear-sight plate design. SIG XRAY-style day/night tritium sights include a green tritium front dot and two tritium rear dots, with an approximate 6.6 in sight radius.
Built on Sig’s modular, removable FCU, this P320 supports caliber and size conversions within the platform. The polymer frame integrates a dust cover with a 4-slot M1913/Picatinny rail for mounting a light or accessory. There is no external manual thumb safety, and the operating system is a locked-breech, tilting-barrel design.
Chambered in 9mm Luger with a 17+1 capacity, this full-size pistol measures 8.2 in in overall length, 5.5 in in height, and 1.3 in in width, with a weight of approximately 29.5–29.6 oz. Markings include a slide roll mark "SIG SAUER P320," a barrel hood marked "9mm x 19," and a frame molded "NEWINGTON, NH, USA."
