XS Sights R3D Features The XS Sights R3D Night Sights set is built around a traditional 3-dot tritium sight picture that gives shooters a familiar front-post-and-notch reference under any lighting condition. The front sight combines a tritium insert with a Green glow surrounded by an Orange outline making it easy to distinguish quickly from the rear sight dots during fast target transitions. A photoluminescent element in the front sight absorbs ambient light throughout the day allowing it to glow brightly in low light even without relying solely on tritium decay. This combination gives shooters a sight picture that performs well across a wide range of lighting scenarios from bright daylight to total darkness. The rear sight uses a wide notch design paired with an anti-reflective lens that cuts down on glare bouncing back into the shooter s eye helping maintain a clear sight picture under harsh lighting. Both sights are Green in configuration giving a consistent easy-to-read reference that many shooters find faster to acquire than traditional white dot setups. Built specifically to fit the Glock 42 43 43X and 48 pistols these sights are proudly manufactured in Fort Worth Texas. Packaged 20 to a bulk pack this set is well suited for dealers instructors or armorers equipping multiple Glock subcompact pistols with a reliable American-made night sight option.
