Built on the modular P320 platform, this XSeries XFULL PRO configuration pairs a stainless-steel slide with a factory black finish and a full-size XSeries polymer grip module. The grip includes an extended beavertail and a high undercut to support a consistent, high hold. A flat-faced trigger and striker-fired action deliver the XSeries control setup, and the pistol deletes the external manual thumb safety.
The slide is optics-ready with a direct-mount footprint and comes equipped with a factory-installed SIG Sauer ROMEO-X red dot. It also features front and rear cocking serrations for positive manipulation. The front sight is a blade with a high-visibility green ring, and the rear sight is obscured by the mounted optic.
Capacity is 17+1 in 9mm Luger, and this example includes three factory steel SIG P320 magazines made in Italy. The dustcover integrates a 3-slot Picatinny/M1913 accessory rail for lights or other compatible accessories.
This pistol was issued for law enforcement personnel and later released as surplus to the civilian market. It includes its SIG Sauer factory hard case, and the case label serial matches the pistol's serial. Controls include ambidextrous slide catch levers, and the overall package reflects the XSeries XFULL PRO's full-size duty configuration made in the USA.
