The SIG SAUER M18 is the compact sidearm selected by the U.S. military across all branches, and this version pairs that pedigree with an X-Series grip module for an enhanced hold and a black finish in place of the standard coyote. Built on the modular P320 fire-control chassis with a 3.9-inch barrel, it wears an optics-ready slide, SIGLITE night sights, and a manual thumb safety per military specification. Chambered in 9mm with generous capacity, the M18 delivers genuine service-pistol credentials in a carry-friendly footprint.
