The XFULL PRO configuration delivers the full-size 4.7-inch setup with a 17+1 capacity in 9mm Luger. It is striker-fired with no external manual safety and a left-side magazine release, paired with ambidextrous slide catch levers for straightforward operation.
The optics-ready slide includes a removable cover plate and front and rear cocking serrations for confident manipulation. Sight alignment is handled by day/night iron sights, with a green-outline front dot and a two-dot rear, both dovetailed.
The XSeries flat-faced trigger promotes a consistent, straight-back press. The polymer grip module displays the SIG medallion and an extended beavertail for secure control. A 3-slot Picatinny/M1913 accessory rail is integrated into the dust cover.
Built on SIG's modular, removable FCU design, this P320 allows the serialized fire control unit to be moved between compatible grip modules and configurations. The pistol is marked NEWINGTON, NH, USA, and ships with three 17-round steel magazines, providing ample capacity out of the box.
