Sig Sauer M18 Coyote OR Compliant Compact Handgun 10rd Magazines(3) 3.9" Barrel Manual Safety

The Sig Sauer M18 Coyote is a compact 9mm handgun built on the same platform trusted by the U.S. Marine Corps and military branches worldwide. This commercial release brings proven military reliability to civilian shooters who demand a dependable carry gun or duty backup. With a 3.9-inch barrel, coyote tan finish, and manual safety, the M18 strikes the balance between firepower and portability that working professionals and serious sport shooters appreciate.

Built from stainless steel throughout, the M18 features SIGLITE night sights and an optic-ready slide compatible with the ROMEO-M17 red dot system—no gunsmithing required. The striker-fired trigger is smooth and predictable, and the M1913 accessory rail gives you mounting options for lights or lasers. You get three 10-round steel magazines, each designed for reliability through thousands of rounds. The standard medium grip module in coyote tan matches the slide, and the manual safety adds a layer of security for carry or home defense.

Whether you're outfitting a duty belt, looking for a reliable compact carry gun, or want to run red-dot optics on a purpose-built platform, the M18 delivers the same performance that's backed by military specification. It's a no-compromise choice for shooters who value accuracy, durability, and real-world usability over trend or gimmick.
