Sig Sauer P320X Full 9mm

Updated August 24, 2026

This SIG Sauer P320 X-Full semi-automatic pistol is chambered in 9mm and comes equipped with a SIG Sauer ROMEO red dot sight, making it a desirable optic-equipped example of the popular X-Series platform. Serial number 58H309606, this pistol features an approximately 4.5" barrel with a shiny bore and remains in good overall condition. The full-size polymer X-Series frame incorporates an aggressively textured synthetic grip and is paired with a steel slide carrying the mounted SIG Sauer ROMEO optic. Three magazines are included along with the original SIG Sauer hard case, creating a particularly complete package. The modular P320 has become one of SIG Sauer’s signature modern handgun designs, while the X-Full configuration provides upgraded ergonomics and a more performance-oriented feel. With three magazines, factory case, factory-brand optic, shiny bore, and full-size proportions, this is a nicely equipped SIG package with strong auction appeal. Please see photos.
