SIG Sauer P320 M17 9mm Full-Size, Coyote, 4.7 in Barrel, 17+1, Optic-Cut Slide, Ambi Safety
This full-size SIG Sauer P320 M17 is the civilian counterpart to the U.S. Army's M17 Modular Handgun System. It features a coyote-colored slide and frame, a 4.7-inch barrel, and the P320's modular, serialized fire-control unit. The pistol includes an ambidextrous manual thumb safety, ambidextrous slide catch/release, an optic-cut slide with a removable rear-sight cover plate, and a Medium-size grip module. Made in the USA, it offers a 17+1 capacity and comes with two factory 17-round magazines.
The slide provides front and rear serrations and an external extractor, while the dustcover integrates a three-slot MIL-STD-1913 Picatinny accessory rail. Sights include a front blade with a single dot and a rear notch integral to the removable optic cover plate. The combination of modular design, duty-ready controls, and coyote finish marks this M17 variant as a strong representation of the service pattern.
