Sig Sauer P320X Full 9mm

Updated August 24, 2026

This SIG Sauer P320 X-Full semi-automatic pistol is chambered in 9mm and offers the performance-oriented ergonomics of the X-Series in a full-size configuration. Serial number 58J406665, 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 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. Three magazines are included along with the original SIG Sauer hard case, making this a nicely complete package. The P320 has become one of SIG Sauer’s most recognizable modern handgun platforms due to its modular design, while the X-Full configuration adds more refined ergonomics and a competition-inspired feel. With three magazines, factory case, optic-ready slide, shiny bore, and popular 9mm chambering, this is a strong and appealing SIG package. Please see photos.
