XS Sights GLR014P6G R3D Night Sights fits Glock Black |

R3D Night Sights feature traditional 3-dot tritium, notch and post, sight picture. The tritium front sight comes equipped with our proprietary photoluminescent orange or green Glow Dot, which absorbs ambient light and glows in low light. The 2-dot tritium blacked-out rear illuminates, giving proper sight alignment while not outshining the front sight for accurate indexing. Our design increases focus on the front sight by using a brighter tritium vial in the front and using the tritium’s light to charge the Glow Dot slightly. This slight difference makes the front sight glow more brightly than the two tritium vials in the rear, keeping your focus downrange. XS R3D Tritium Night Sights are an excellent notch and post sight picture that will keep your front sight visible day or night. That way, you’ll be ready for the fight, no matter the light.
