XS Sights R3D 2.0 Glock 42/43/43X/48 Orange Front

The XS Sights R3D 2.0 night sight set is designed for Glock 42, 43, 43X, and 48 pistols. It combines green tritium front and rear lamps with an orange photoluminescent front outline for a high-contrast notch-and-post sight picture in changing light. The set is suited to everyday handgun use and standard holster configurations.

The serrated rear sight helps reduce glare, while its wide notch provides visibility around the front post. A rear ledge supports one-handed slide operation, and the black Nitride finish provides resistance to wear and corrosion.
