The P320 XFULL PRO pairs a full-size XSeries grip module with a 4.7-inch barrel for a 17+1 capacity in 9mm Luger. It uses Sig's striker-fired action and a flat-faced trigger, delivering a consistent pull within the P320 modular system. There is no external manual safety on this configuration.
The slide is factory optic-ready and ships with a cover plate that retains the rear sight. Front and rear slide serrations aid manipulation. SIG X-RAY 3 day/night sights include a square post front with a bright green ring and a rear black notch with small inserts for low-light reference.
Construction details include a matte black slide, a polymer grip module with SIG medallion inserts, and a stainless steel receiver chassis. A three-slot accessory rail on the dustcover supports weapon-mounted lights or accessories compatible with the rail profile.
