XS Sight Systems R3D 2.0 Night Sights for Glock 20/21/29/30/30S/37/40/41 – Green Tritium Front, Black Rear

Upgrade your full-size and compact Glock with the XS Sight Systems R3D 2.0 Night Sights, engineered for low-light precision and fast target acquisition. Featuring a tritium-powered green front sight paired with a photoluminescent glow dot, these sights absorb ambient light and continue glowing even when tritium illumination alone isn’t enough. The wide notch rear sight with serrations and an anti-reflective lens reduces glare and frames the front sight quickly under stress. A traditional 3-dot tritium night sight configuration provides a familiar sight picture trusted by shooters and professionals alike. Built to last, the R3D 2.0 features a corrosion-resistant Black Nitride surface finish and is proudly manufactured in Fort Worth, TX. Compatible with Glock Gen 1–5, including MOS models, and fits the Glock 20, 21, 29, 30, 30S, 37, 40, and 41.
