Description
SIG Sauer P320-M17 9mm Coyote MA Compliant Pistol, 4.7" Barrel, 10-Round
The SIG M17 is the full-size military P320. Coyote, optic-ready, and built around a 4.7 in. barrel, it is the full-size MHS P320 as issued to the U.S. military.
The M17 uses the longer slide, not the carry-size M18. A factory ROMEO-M17 is installed only when this page says so. These pistols ship to a licensed FFL.
This configuration
The stainless slide is optic-ready and ships with a SIGLITE front night sight and a removable night-sight rear plate. The ROMEO-M17 is designed for M17/M18 MHS slides; other pistol optics fit only when they match this plate and cut. That is not a universal P320 footprint, and an optic is not included. This configuration uses 10-round magazines rather than the 17-round and 21-round magazines supplied with unrestricted M17 CSS pistols. The coyote polymer grip module has an M1913 accessory rail. The slide on this P320-M17 uses the earlier commercial marking, distinct from current M17 CSS slides.
What ships
A factory optic is installed only when this page says so. This item ships to a licensed FFL. See the SIG M17 collection.
