The XFULL configuration delivers a full-size grip and 4.7 in barrel for a standard 17+1 capacity in 9mm Luger. The XSeries flat-faced trigger promotes a straight, consistent pull, while the striker-fired action keeps operation simple and reliable.
The slide is optics-ready with a removable cover plate cut for the SIG Pro/R2 footprint, and it includes front and rear serrations for positive manipulation. Steel XRAY3 Day/Night 3-dot sights come installed, with tritium vials and a high-visibility green front ring for fast sight acquisition in varied lighting.
Ergonomics and control are emphasized with an ambidextrous slide catch and a reversible magazine release. The XSeries polymer grip module features the M backstrap and an integral flared magwell to streamline reloads.
Built on SIG’s modular platform, this P320 uses a serialized stainless-steel chassis (FCU) inside a polymer grip module, with a full-length dust cover and M1913/Picatinny accessory rail for lights or other rail-mounted accessories. Made in the USA; mfg part number W320F-9-BXR3-PRO-RXX.
