XS Sights R3D night sights for Glock bring a proven 3-dot sight picture to the fight—day or night. Built around tritium illumination and a proprietary photoluminescent glow dot, these sights are engineered to keep your focus exactly where it needs to be: on the front sight. The front sight features green tritium paired with an orange outline glow dot that absorbs ambient light and glows in low-light conditions, while the blacked-out rear carries two tritium vials that illuminate without overwhelming the front sight picture. This intentional brightness hierarchy forces your eye downrange and locks in proper alignment even when light is scarce. Whether you're training at dusk, responding in dim indoor spaces, or navigating true darkness, R3D sights deliver a fast, reliable sight picture.
The design philosophy is straightforward: tritium in the front sight is slightly brighter than the rear pair, and the glow dot gets a subtle charge from that same tritium vial. That small but deliberate difference keeps the front post visually dominant, letting your brain work faster and more intuitively. This is the kind of engineering that matters when seconds count. The sights are CNC machined from steel in a matte black finish, built tough for carry guns and duty weapons alike.
XS Sights R3D night sights fit Glock 42, 43, 43X, and 48—popular compact and subcompact models that demand reliable low-light performance. If you carry one of these Glocks for self-defense or duty use, upgrading to night sights removes a critical weakness: the inability to quickly align your gun in low light. These sights don't require batteries, don't need adjustment, and will work the same way five years from now as they do today.

XS Sights R3D night sights are designed for Glock 42, 43, 43X, and 48. These are all single-stack compact and subcompact models. Do not attempt to install on full-size or mid-size Glocks.
The tritium vials in both the front and rear sights contain a radioactive isotope that continuously emits a faint glow without any external power. In complete darkness, the tritium alone provides a visible sight picture. The photoluminescent orange glow dot on the front sight requires some ambient light to charge; it glows brightest in low light (dusk, indoor shadows, artificial light) but the tritium itself works in any light condition, including total darkness.
XS Sights intentionally made the front tritium brighter and paired it with a glow dot to ensure your eye naturally focuses on the front post. In defensive or tactical shooting, speed comes from a consistent sight picture with the front sight as the dominant visual element. The brighter front prevents the rear sights from drawing your attention and degrading your target acquisition time.
The product is a complete front and rear sight set for your Glock. Installation requires basic gunsmithing tools or a qualified armorer; the sights themselves are the complete package.
