Trijicon GL101 Bright & Tough Night Sights Green Tritium Glock 17/19

The Trijicon Bright & Tough Night Sights deliver reliable target acquisition in complete darkness through self-luminous tritium inserts. These factory-grade sights eliminate the guesswork of low-light shooting with consistent green illumination that requires no batteries or external light sources.

What Makes This Different

Unlike standard three-dot configurations, these sights feature tritium-filled glass lamps sealed in aluminum cylinders for maximum durability. The white outline rings provide enhanced visibility in daylight conditions while the tritium maintains effectiveness for 12+ years. Swiss-made tritium lamps deliver consistent brightness output rated at 10-15 millicuries per lamp, significantly brighter than economy alternatives.
