XS Sights R3D Night Sights for Glock Large Frame – Green Front Tritium

The XS Sights R3D night sight set delivers 24-hour visibility with a tritium-powered green front sight surrounded by a high-contrast photoluminescent glow ring. Designed for Glock large frame pistols, the R3D combines fast target acquisition in daylight with reliable illumination in low-light or no-light conditions. The rear sight features a shallow V-notch with tritium inserts for rapid sight alignment.

Machined from steel with a rust-resistant finish, the R3D installs using a standard sight pusher or armorer's tool. The front sight's Ember Glow Dot technology absorbs ambient light and glows in darkness, while the tritium lamp provides consistent illumination for 10-12 years. This sight set fits Glock models 17, 19, 22, 23, 24, 26, 27, 31, 32, 33, 34, 35, 37, 38, and 39 (excluding MOS models). Ideal for concealed carry, duty use, and home defense where speed and reliability matter.
