Sig Sauer P320X Full 9mm

Updated August 24, 2026

This SIG Sauer P320 X-Full semi-automatic pistol is chambered in 9mm and offers a full-size, performance-oriented configuration with desirable factory accessories. Serial number 58J406700, 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, providing a ready mounting point for a compatible electronic sight. Three magazines are included along with the original SIG Sauer hard case, adding considerable completeness and value to the package. The P320 platform has become a cornerstone of SIG Sauer’s modern pistol lineup due in large part to its modular construction, while the X-Series builds on that foundation with upgraded ergonomics and styling. With three magazines, factory case, optic-ready slide, full-size frame, and shiny bore, this is a strong modern SIG Sauer offering. Please see photos.
