Sig Sauer P320X Full 9mm

Updated August 24, 2026

This SIG Sauer P320 X-Full semi-automatic pistol is chambered in 9mm and comes configured with a premium optic and several desirable accessories. Serial number 58J408180, this example features an approximately 4.5" barrel with a shiny bore and remains in good overall condition. The pistol utilizes SIG Sauer’s X-Series polymer grip module and full-size frame paired with a steel optic-cut slide, creating the familiar performance-oriented configuration of the P320 X-Full family. Mounted to the slide is a Trijicon RMR06 red dot sight, a highly regarded optic that adds considerable appeal to this already desirable package. Three magazines are included along with the original SIG Sauer hard case. The P320 has become one of SIG Sauer’s most important modern handgun platforms, while the X-Series expanded the design with upgraded ergonomics and a more competition-inspired feel. With three magazines, factory case, optic-ready slide, and premium Trijicon glass already installed, this example offers significantly more than a standard factory pistol. Please see photos.
