XS Sights GLR201P6G R3D 2.0 Night Sights for Glock - Green Tritium

The XS Sights GLR201P6G R3D 2.0 Night Sights transform target acquisition in low-light conditions with advanced tritium technology. These precision-engineered sights deliver consistent performance when visibility matters most, featuring a distinctive green tritium front sight with photoluminescent outline paired with a matching green tritium rear sight.

What Makes This Different

The R3D 2.0 design incorporates a shallow V-notch rear sight that naturally draws the eye to the front sight, creating faster target acquisition than traditional square-notch configurations. The front sight measures 0.145 inches wide with a prominent green outline that charges from ambient light and glows bright in darkness. This dual-illumination system provides visibility in all lighting conditions, from bright daylight to complete darkness.

Key Features

• Green tritium vials rated for 12-year illumination with consistent brightness
• Photoluminescent green outline on front sight charges from ambient light
• Shallow V-notch rear configuration for rapid sight alignment
• Steel construction with corrosion-resistant finish
• Direct replacement for factory Glock sights - no modifications required
• Compatible with most holsters designed for factory sight profiles
• Front sight height: 0.180 inches, rear sight height: 0.165 inches

Field testing demonstrates reliable performance across temperature ranges from -20°F to 150°F without brightness degradation. The tritium capsules maintain consistent illumination through thousands of rounds, while the steel construction withstands repeated holster draws and environmental exposure. Law enforcement agencies and competitive shooters rely on these sights for duty carry and precision shooting applications where split-second target identification is critical.
