Sig Sauer P320 X-Full | 9mm | 4.7″ | 2x17rd | 320XF-9-BXR3-RXX

The Sig Sauer P320 X-Full is a full-size XSeries handgun chambered in 9mm with a 4.7″ slide and barrel. It ships with a factory-mounted ROMEO-X reflex sight and two 17-round magazines, and features an XSeries grip module with an extended beavertail and deep undercut for a higher grip. This pistol is suited for everyday carry (EDC) and range/target shooting where controllability and sight acquisition are priorities. Suggested optic: the included SIG ROMEO-X reflex sight pairs directly with the slide cut and remains a practical choice under $1000.

This model is striker-fired and is not offered with a manual thumb safety. The pistol includes XRay3 day/night sights and a rear sight plate assembly that supports direct mounting of common reflex optics; the optic footprint is SHIELD/RMSc. Follow all safe firearms handling practices at all times, including treating every firearm as loaded and keeping your finger off the trigger until ready to fire.
