XS Sights R3D 2.0 Night Sights for GLOCK 21 – Orange Front Dot

The XS R3D 2.0 night sights deliver a high-contrast aiming solution for GLOCK 21 pistols, combining tritium illumination with a bold orange front dot for rapid target acquisition in any lighting condition. The front sight features a photoluminescent Glow Dot ring surrounding a tritium vial, while the rear sight uses a blacked-out tritium configuration to minimize distraction and drive focus to the front post. This setup works equally well for defensive applications and low-light range work.

Designed as a direct replacement for factory GLOCK sights, the R3D 2.0 installs using a standard sight pusher tool (rear) and requires no permanent modifications to the slide. The front sight is staked in place for secure retention under recoil. Constructed from CNC-machined steel with a protective finish, these sights are built to withstand hard use and maintain zero through thousands of rounds.
