The XCompact XSeries configuration delivers a compact, carry-friendly footprint with a 3.6-inch barrel and a Nitron-finished slide featuring front and rear serrations and an optics cut. The serialized fire control unit (FCU) anchors the modular P320 design, allowing the grip module to be easily swapped while maintaining the same core, serialized component.
A SIG Sauer ROMEO1 PRO red dot is installed in place of the rear sight plate area, paired with a front tritium sight (TG-H3) that has a high-visibility green ring. As configured, there is no rear iron sight because the optic is mounted. The ROMEO1 PRO protective shroud and slip-on cover are included.
The XSeries polymer grip module provides an extended beavertail, a high undercut trigger guard, and a lightly flared internal magwell for secure control and smooth magazine changes. A flat-faced XSeries trigger supports consistent, straight-back press. The dustcover integrates an M1913 Picatinny accessory rail, and this pistol arrives with a SIG Sauer FOXTROT1X weapon light installed.
Short-recoil operated and striker-fired, this P320 is chambered in 9mm Luger with a 15+1 capacity. Markings include the frame stamped NEWINGTON, NH, USA; slide marked SIG SAUER P320; and barrel hood marked 9mm x 19. Country of origin is USA.
