XS R3D 2.0 Night Sights for Glock 42/43/43X/48

The XS Sights R3D 2.0 night sight set is designed for Glock 42, 43, 43X, and 48 pistols. It combines a green tritium front sight with a photoluminescent green outline and a tritium-equipped rear sight for a traditional three-dot sight picture in changing light conditions.

The CNC-machined steel sights use a corrosion-resistant Black Nitride finish. A serrated rear sight, anti-reflective lens, and rear sight ledge support a clear sight picture and practical everyday use.
