Sig Sauer M18 CSS 9mm Luger 3.9" 10+1 Semi-Auto Pistol - Coyote PVD

The Sig Sauer M18 CSS is the commercial-market release of the 9mm Luger striker-fired service pistol adopted by the U.S. Armed Forces, built on Sig Sauer's proven P320 modular platform. This compact carry pistol pairs a 3.9" barrel with a medium polymer grip module and a 10+1 capacity, all wearing the distinctive Coyote PVD finish.

The M18 CSS carries over the MHS (Modular Handgun System) slide geometry from the military-issue variant, including an optic-ready slide cut and a single-screw sight plate compatible with popular red dots like the Delta Point Pro and Romeo-M17. The slide is serrated for confident manipulation, and the striker-fire action delivers a clean, consistent trigger pull characteristic of the P320 family.

Built around a polymer frame with the Coyote PVD finish, the M18 CSS ships with three 10-round magazines, making it ready for range sessions or defensive carry right out of the box. As a complete, optic-ready compact 9mm, the M18 CSS is well suited for home defense, duty use, or everyday carry.
