Configured in the XSeries, this full-size P320 pairs a flat XSeries trigger with the XSeries full-size grip module. The grip features an extended beavertail, high undercut, aggressive texture, and a SIG medallion inlay for secure control and a consistent trigger reach.
The stainless-steel slide wears a Nitron PVD finish and includes front and rear cocking serrations. It is cut for the PRO optic footprint, and the included SIG ROMEO-X red dot is direct-mounted to that cut. The ROMEO-X uses an aspherical lens, and a SIG XRAY3 day/night front sight with a green ring remains in place.
The 4.7 in slide and barrel deliver a full-size sight radius and 17+1 on-board capacity. An integral 3-slot Picatinny rail on the dust cover supports weapon-mounted accessories. The design allows takedown without a trigger pull.
Built on the modular P320 FCU architecture, this pistol accepts caliber and size conversions within the P320 ecosystem. Provenance is law enforcement issue with surplus availability for civilian purchase, and the case label indicates recent production.
