The SIG M17 Romeo-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
It uses a coyote X-series grip module with a magwell and a flat-blade trigger. SIGLITE sights can co-witness with the optic. The ROMEO-M17 is an M17/M18 MHS enclosed 1×24 sight with a 2 MOA red dot and 32 MOA red circle. This configuration is Off-Duty LE Only. Confirm program eligibility with your dealer before ordering. Magazines are a mixed 17-round and 21-round package. If you want the commercial X-series carry-size package with three 21-round magazines, compare the M18X.
