XS Sights R3D 2.0 Night Sights for Glock 19 – Green Front Tritium Dot

The XS Sights R3D 2.0 delivers fast sight acquisition in any light with a high-contrast tritium front dot and blacked-out rear. The green tritium front sight glows continuously for 10-12 years without batteries, while the photoluminescent glow ring charges under ambient light for enhanced visibility in transition lighting. Purpose-built for rapid target engagement on defensive handguns.

Precision-machined steel construction with a proprietary Fortress Finish provides corrosion resistance and reduced glare. The rear sight features a vertical ledge for emergency one-handed slide racking. Direct fit for Glock 19 and other compatible models with no gunsmithing required—front sight uses factory screw, rear sight installs with included key. Standard height for use with factory slide profiles.
