The Sig Sauer M18X CSS 9mm Coyote 3.9" delivers a compact, duty-inspired sidearm built around a striker-fired action and steel frame for confident control. Chambered in 9mm with a 3.9" barrel and coyote PVD treatment, this semi-auto pistol blends everyday carry dimensions with the shootability of a full-size grip and generous 21+1 capacity.

This M18X CSS configuration features coyote polymer grips over a steel frame, fixed Siglite front and rear sights, and three included 21-round magazines, making it ready for extended range sessions right out of the box. Its size and capacity make it well suited for home protection, concealed carry with appropriate holsters, and regular training at the range. Backed by Sig Sauer’s reputation for modern engineering and consistent performance, the M18X CSS is designed for shooters who value reliability and familiar ergonomics.
