The P320-M17 pairs a full-size 4.7 in carbon steel barrel with a carry-length grip module to deliver a duty-length slide while maintaining excellent magazine capacity. The coyote PVD slide features front and rear serrations and an MHS-spec optics cut, and this example includes a factory SIG romeo-x PRO red dot already mounted.
Controls are fully ambidextrous, including the manual thumb safety and slide catch levers, supporting left- or right-handed operation. The M1913 accessory rail on the frame accommodates lights or other rail-mounted gear.
At the core is SIG's modular, serialized fire-control unit housed in a stainless steel receiver, allowing the end user to change grip modules or complete upper assemblies without new serialization. The striker-fired action and fixed front sight combine with the romeo-x PRO red dot for a clear, fast sight picture; iron-sight configuration may vary with the installed optic/plate.
Finished in coyote PVD with a matching coyote polymer grip module, this model adheres to the M17 aesthetic. It is chambered in 9mm Luger with a 21+1 capacity using the extended magazines, and ships with a mix of extended and standard-length steel magazines compatible with the P320/M17 pattern.
