Sig Sauer P320X Full 9mm

Updated August 24, 2026

This SIG Sauer P320 X-Full semi-automatic pistol is chambered in 9mm and combines full-size proportions with the enhanced ergonomics of SIG Sauer’s X-Series platform. Serial number 58J406696, this example features an approximately 4.5" barrel with a shiny bore and remains in good overall condition. The pistol utilizes an X-Series polymer frame with an aggressively textured synthetic grip paired with a steel optic-cut slide, allowing the next owner to install a compatible red dot sight. Two magazines are included along with the original SIG Sauer hard case. The P320’s modular design helped establish it as one of SIG Sauer’s most important modern handgun platforms, while the X-Series adds a more refined, performance-oriented grip and frame configuration. With its optic-ready slide, two magazines, factory hard case, shiny bore, and popular 9mm chambering, this is a well-rounded example of the P320 X-Full family. Please see photos.
