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 premium optic and several desirable factory accessories. Serial number 58J406694, this example features an approximately 4.5" barrel with a shiny bore and remains in good overall condition. The pistol utilizes SIG Sauer’s textured X-Series-style synthetic grip module and polymer frame configuration paired with a steel slide. The slide is optic-cut and currently wears a Trijicon RMR06 red dot sight, a premium optic that adds considerable appeal to this already desirable full-size P320 configuration. Three magazines are included along with the original SIG Sauer hard case, making this a particularly well-equipped package. The modular P320 platform became one of SIG Sauer’s most important modern handgun designs, while the X-Series expanded upon the concept with performance-oriented ergonomics and features. Between the Trijicon optic, three magazines, original case, full-size configuration, and popular 9mm chambering, this is a P320 package with plenty to offer the SIG enthusiast. Please see photos.
