XS Sight Systems R3D Night Sights for Glock 42/43/43X/48 - 3-Dot Orange Tritium

The XS Sight Systems R3D night sight set delivers a 3-dot orange tritium aiming reference built specifically for Glock 42, 43, 43X, and 48 pistols. Designed around a traditional post-and-notch sight picture, these self-illuminating iron sights give defensive shooters a fast, intuitive sight alignment in any lighting condition without relying on batteries or charged electronics.

Each lamp in the front and rear sights is powered by tritium, producing three glowing dots that hold their brightness for years. The front sight pairs its tritium lamp with a high-contrast orange ring that frames the post and speeds target acquisition, while a photoluminescent glow-dot absorbs ambient light and continues to glow in the darkest conditions. The rear sight uses an overhang design that draws the eye toward the front post for a clean, precise sight picture.

Built for direct drop-in fitment on Glock 42, 43, 43X, and 48 pistols, the R3D sights install using a standard sight pusher tool. From everyday concealed carry to low-light home defense, this set delivers reliable defensive sight performance right out of the box.
