AmeriGlo Classic Tritium Sight Set for Glock MOS, Green/White Front, Yellow/White Rear

The AmeriGlo Classic Tritium Sights for Glock MOS (brand part number GL121) pair a green tritium lamp with a white outline on the front sight with two yellow tritium lamps and white outlines on the rear sight, a color-contrast layout that makes the front dot easier to pick out at a glance. It’s the original standard in self-luminous night sights, requiring no battery and no charging, just a steady glow day or night. The Classic 3-dot design is the most widely used sight picture among personal defense shooters, military units, and law enforcement alike, and this set fits the Glock MOS slide.
