FMK Mach 9 G3 Pistol | 9mm | 4 in | OD Green

The FMK Mach 9 G3 is a compact, optic-ready 9mm semi-automatic pistol built on an OD green polymer frame with a serrated, optics-cut slide and a polished stainless steel barrel. It features a 4-inch barrel and an integrated Picatinny rail for accessories. The low barrel profile and textured backstrap are intended to improve point-and-shoot ergonomics and manage muzzle flip. Pair this platform with a Vortex Venom red-dot (well under $1,000) for a reliable sighting solution that mounts to the G3’s factory-cut slide.
