Sig Sauer P320 M17 9mm

Updated August 24, 2026

This SIG Sauer P320 M17 semi-automatic pistol is chambered in 9mm and represents the commercial counterpart to the U.S. military’s modern service-pistol configuration. Serial number M17A037566, this example features an approximately 4.5" barrel with a shiny bore and remains in good overall condition. The pistol utilizes a distinctive FDE-colored polymer frame with a textured synthetic grip paired with a matching-toned steel slide. The slide is optic-ready, allowing the addition of a compatible electronic sight and further enhancing the modern military-inspired setup. No magazine is included. The M17 traces directly to SIG Sauer’s success in the U.S. military Modular Handgun System competition, where the P320 platform was selected as the basis for the new service pistol. That connection gives the model strong military and collector appeal. With its FDE finish, optic-ready slide, shiny bore, and unmistakable M17 identity, this is a desirable modern SIG Sauer offering.
