Sig Sauer M17 M17-9-CSS-MS-10 | 9mm | 4.7″

The Sig Sauer M17 (M17-9-CSS-MS-10) is the commercial MHS-format full-size service pistol offered in a Coyote PVD finish with a 4.7-inch barrel. It ships optic-ready with a slide configuration compatible with the ROMEO-M17 and DeltaPoint Pro footprints and includes three 10‑round magazines and a manual safety. A SIG Romeo-M17 red dot is a practical optic choice that pairs directly with the factory footprint and remains comfortably under $1,000.

Typical applications include duty/service use and range/training work where optic-ready modularity and consistent ergonomics are priorities.
