Upgrade your compact Glock’s low-light capability with the XS Sight Systems R3D 2.0 Suppressor Height Night Sights, engineered specifically for the Glock 42, 43, 43X, and 48. Proudly manufactured in Fort Worth, TX, these sights deliver a proven 3-dot tritium sight picture combined with a photoluminescent glow dot that absorbs ambient light and glows brilliantly in low-light conditions—giving you reliable target acquisition whether the lights are on or off.

The suppressor-height profile makes these sights fully compatible with standard suppressors and RMR optic-cut MOS models across Glock Gen 1–5, so they’re ready to work with your current or future setup. The wide notch rear sight features precision serrations and an anti-reflective lens to minimize glare and maximize sight clarity under any lighting condition. A durable Black Nitride surface finish provides long-lasting corrosion resistance, making these sights tough enough to handle everyday carry and demanding range sessions alike.
