About this product

The FMK Mach 9 G3 is a compact 9mm pistol with a 4-inch barrel and optics cut. It’s a solid choice for Pennsylvania concealed carry, home defense, or a day at the range. Built with a polymer frame and a low-profile slide, it’s designed for comfortable shooting and quick target acquisition.

The FMK Mach 9 G3 is a 9mm semi-automatic pistol featuring a 4-inch barrel and a factory-cut slide for micro red dot optics. This pistol is suitable for concealed carry, home defense, or use at a Pennsylvania shooting range.

  • Slide: Optics-cut, serrated

The Mach 9 G3’s slide is compatible with common micro red-dot sights like the Burris Fastfire 3, Vortex Viper/Venom, and Trijicon RMR.
