XS Sight Systems R3D Night Sights for Glock 17/19

XS R3D Night Sights: Always Ready, Day or Night

The XS R3D represents a thoughtful evolution in combat sighting systems. These night sights employ a traditional 3-dot tritium design—notch and post—that has proven itself in the field for decades.

Key Features

• Tritium Illumination: Green tritium vials in both front and rear sights provide reliable low-light visibility without external power
• Ember Glow Dot Technology: The front sight features an orange photoluminescent ring that absorbs ambient light and glows in darkness, charged by the tritium lamp itself
• Contrast-Focused Design: Blacked-out rear sight increases contrast and keeps your focus on the front sight—where it belongs
• Brightness Hierarchy: Brighter front tritium vial ensures the front sight glows more prominently than the rear at all times
• Snag-Free Profile: Designed for smooth draws and reliable operation

Why R3D Sights Matter

These sights excel in both bright daylight and low-light scenarios. The combination of tritium and photoluminescent technology ensures you maintain a clear sight picture whether you're at the range in full sun or responding to a threat in dim conditions. The notch-and-post design is intuitive and fast—ideal for defensive shooting where every millisecond counts.
