XS Sights R3D Night Sights SIG Sauer Springfield Green Tritium

The XS Sights SIR015P6G R3D Night Sights deliver 24-hour sight visibility with Swiss tritium inserts that maintain brightness for 12+ years. These precision-machined steel sights feature a distinctive green tritium front dot with photoluminescent outline that charges in daylight and glows in darkness.

What Makes This Different

Unlike standard three-dot configurations that can create sight confusion under stress, the R3D system uses a single bright front sight paired with a shallow V-notch rear. The front sight's photoluminescent ring absorbs ambient light during the day, creating a bright white outline that transitions to green glow in low light. This design reduces sight alignment time by 30% compared to traditional setups while maintaining precision accuracy.

Key Features

• Swiss tritium vials rated for 12-year brightness guarantee
• Photoluminescent front sight outline charges in daylight, glows green in darkness
• CNC-machined from bar stock steel with Melonite finish
• Fits SIG Sauer P-series and Springfield Armory pistols with #8 rear sight
• Front sight height: 0.180", rear sight height: 0.165"
• Shallow V-notch rear design eliminates sight confusion
• No gunsmithing required - drop-in installation

Field testing shows consistent point-of-impact accuracy across temperature ranges from -20°F to 140°F. The Melonite coating provides corrosion resistance equivalent to hard chrome while maintaining precise tolerances. Law enforcement agencies report faster target acquisition in low-light scenarios, while competitive shooters appreciate the crisp sight picture for precision work. The tritium maintains full brightness through 50,000+ round counts without degradation.
