Featuring SIG SAUER's exclusive slide-mounted optic, the ROMEO1 PRO, the RXP will ensure faster sight acquisition on target. Simply put, it will make a good shooter a great shooter. Shoot confidently with faster target acquisition and improved accuracy. Installed. Zeroed. And backed by the quality of the SIG name.

One of the most popular P320 pistols just got better and joins the Red Dot Revolution.  The P320 XCOMPACT now comes equipped with the ROMEO1 PRO reflex optic right out of the box.  The 3.6” barrel, XSeries slide, flat trigger, and XSeries compact grip module are now joined with a 6MOA slide mounted optic, along with perfectly co-witnessed XRay3 day/night suppressor-height sights.  Additionally, an optic plate cover is included with all Romeo1 PRO-equipped XSeries P320 pistols for shooting without the optic if desired.  The P320 XCOMPACT RXP represents the best balance of precision, comfort, and capability in the CCW market.  Each P320 XCOMPACT RXP comes standard with two (2) 15rd steel mags.
