The SIG Sauer P320 X-Full Max (model 320XF-9-MAXM) is a full-size, striker-fired 9mm Luger pistol that combines the modular P320 platforms known reliability with competition-minded features and duty-ready durability, offering a 3.9-inch carbon steel barrel, matte black DLC stainless slide with optic cut/porting and serrations, and an RX footprint PRO that makes mounting micro red dots straightforward for faster target acquisition. The XSeries flat blade trigger and black full-size XSeries grip module deliver a crisp, consistent break and ergonomic control that shooters appreciate during extended range sessions, defensive drills, or service use, while XRAY3 day/night sights provide a clear sight picture whether training crosswind routines or running low-light scenarios. At roughly 33.2 oz and an overall 8.3-inch length the platform balances controllability with sight radius for competition stages and practical defensive shooting, and its 21+1 capacity gives sustained follow-up fire when needed. Built on the P320 familys serialized fire control and requiring FFL transfer, this SIG Sauer semi-auto pistol is aimed at users seeking a modern, optic-ready duty/competition pistol with durable finishes and match-oriented ergonomics.
