Originally issued to law-enforcement personnel and later released as surplus, this XFULL Pro brings duty-ready configuration to the civilian market. It arrives in as-new condition and includes an installed SIG ROMEO-X optic, providing a turnkey setup with factory components.
The XSeries frame delivers enhanced control with an extended beavertail and a deep triggerguard undercut. A flat-faced XSeries trigger and striker-fired action support consistent, predictable operation. The pistol has no manual thumb safety and includes an M1913 accessory rail for mounting lights or lasers.
The Pro-cut slide features forward and rear serrations and a black Nitron finish. It is cut for SIG’s PRO-footprint optics and comes equipped with fixed steel sights, including a green-ring front sight and a steel rear notch. The 4.7-inch carbon steel barrel and full-size format balance sight radius and recoil control.
As part of the P320 modular platform, the serialized, removable FCU allows the core fire control unit to be transferred between compatible grip modules and slides. The frame is marked NEWINGTON, NH, USA, and overall construction reflects U.S. manufacture.
Capacity is 17+1, and this pistol includes three factory 17-round steel magazines. Combined with the installed ROMEO-X, full-size grip, and duty features, this XFULL Pro is set up for confident use out of the box.
