SIG Sauer P320 M17 9mm MA-Compliant, Alloy Grip, Optics-Ready, Night Sights, 10-Round
This full-size SIG Sauer P320 M17 pairs the U.S. Army–inspired Coyote-tan PVD slide with a black anodized aluminum alloy grip module, giving buyers a lighter, harder-wearing frame and an extended beavertail for better control. It comes MA-compliant with an ambidextrous manual safety and 10-round magazines, yet keeps the duty-grade features that made the M17 famous—modular fire-control unit, night sights, and an optics-ready slide. Factory window cuts reduce slide weight and add a distinctive look.

The serialized stainless steel fire-control unit is the heart of SIG’s modular P320 system, allowing easy caliber or frame changes while keeping the same serialized component.
An aluminum alloy grip module replaces the standard polymer, offering improved rigidity, an extended beavertail, and aggressive molded checkering for a firm purchase. The module is finished in durable black anodizing that contrasts with the Coyote-tan slide.
The PVD-coated slide arrives factory-milled for optics and accepts the Leupold DeltaPoint Pro or SIG ROMEO-M17 without an adapter plate. Window cuts lighten reciprocating mass, aiding faster cycling and adding ventilation to the barrel.
Controls are fully ambidextrous. A reversible magazine release, ambidextrous manual thumb safety, and ambidextrous slide stop make the pistol equally convenient for right- and left-handed shooters. The flat-faced trigger delivers a straight pull that many shooters find easier to stage.
Factory SIGLITE tritium night sights include a green-dot front and a removable two-dot rear plate that doubles as the optic-cover plate, ensuring a clear, illuminated sight picture out of the box.
