The SIG Sauer P320 XCompact (model P320XC9BXR3RXX10) brings the modularity of the P320 series into a slim, carry-ready package designed for everyday concealed carry, duty use, and range training, with a 3.6" barrel chambered in 9mm Luger and a 10+1 capacity that balances shootability and concealment. The redesigned polymer XCompact grip features a reduced fastback carry cut, low-profile internal magwell, extended beavertail and a high undercut trigger guard to improve hand fit, recoil control and draw comfort for users transitioning from full-size to compact platforms. Optic-ready slide with serrations mates to modern red dot solutions and is fully compatible with the Romeo1PRO footprint while the included Romeo-X Pro reflex optic gives immediate sighting capability for quick target acquisition in low-light or daylight conditions; X-Ray3 Day/Night front sight and a rear night sight plate assembly provide durable backup sighting. As a striker-fired SIG P320 family handgun with black polymer grips, black frame finish and a compact, carry-focused footprint, it suits concealed carry holders, plainclothes officers and shooters seeking a reliable, adaptable semi-auto pistol for defensive and range applications, and will require transfer through an FFL.
