The M17 is the commercial version of the pistol the U.S. Army adopted as its service sidearm, built on SIG's modular P320 chassis. That means a 4.7-inch barrel, a full-size grip module, a manual thumb safety, and an optics-ready slide with a removable plate for mounting a red dot directly. This one wears a black finish.

The P320's serialized fire control unit can be moved between grip modules and slide assemblies, which is what made the platform attractive to the military and remains its most distinctive engineering feature.
