The FMK 9C-G3 comes with an optic ready slide. The design allows mounting of any Burris Fastfire 3, Vortex Viper, Vortex Venom, or Trijicon RMR optics. Each FMK9C1-G3 comes with a polished stainless steel barrel and Fast Action trigger mechanism for the shooting enthusiast who prefer a quick short trigger pull with a drop-free magazine. The backstrap effectively reduces felt recoil and hugs and grips the palm of the shooting hand. The result is a grip that seems to mold to the shooter's hand instead of having to mold your hand to fit the grip. The barrel is engineered to sit low for superior point-and-shoot accuracy and reduced muzzle flip, and the FMK9C1-G3 has virtually no external protrusions. (1) FMK magazine.
