SIG SAUER M18 CSS 9MM | 3.9-inch Coyote

The SIG SAUER M18 CSS is the commercial M18 built to deliver the reliability, accuracy, and durability expected of a service-oriented pistol. It comes standard with SIGLITE night sights and a removable night sight rear plate and is finished in Coyote PVD. The striker-fired, full-size design is suited to everyday carry and professional training environments. For a compact red-dot option under $1000, consider the Holosun 507K to maintain a low-profile sighting solution that matches the M18’s slide footprint.

Applications: everyday carry (EDC) and range training.
