XS Sight Systems R3D 2.0 Night Sights for Glock 42/43/43X/48 – Green Tritium Front, Black Rear

Upgrade your compact or subcompact Glock’s low-light performance with the XS Sight Systems R3D 2.0 Night Sights. Engineered specifically for the Glock 42, 43, 43X, and 48, these American-made sights deliver a reliable tritium front and rear setup with a high-contrast photoluminescent glow dot that absorbs ambient light for enhanced visibility in dim or no-light conditions. The traditional 3-dot tritium notch-and-post sight picture offers an intuitive, familiar aiming experience for both everyday carry and defensive use.

The wide notch rear sight features anti-glare serrations and an anti-reflective lens to minimize distractions and keep your focus on target. A durable Black Nitride surface finish provides excellent corrosion resistance for long-lasting reliability—even under demanding conditions. Compatible with Glock Gen 1–5, including MOS models, the R3D 2.0 is a versatile drop-in upgrade for a wide range of configurations.

Proudly manufactured in Fort Worth, TX, XS Sight Systems has built a reputation for precision, durability, and purpose-driven design trusted by law enforcement and civilian shooters alike.
