Meprolight Tru-Dot Tritium Night Sight Set Glock 17/19/22/23

The Meprolight Tru-Dot Sight Set delivers 24/7 target acquisition with self-illuminating tritium technology. This precision sight system combines a green tritium front sight with a yellow tritium rear sight featuring white outline rings for enhanced visibility in all lighting conditions.

What Makes This Different

Unlike standard polymer sights, the Tru-Dot system uses genuine Swiss tritium gas tubes that maintain consistent brightness for 12+ years without batteries or external light sources. The contrasting green front and yellow rear configuration creates instant sight picture acquisition, while the white outline rear sight provides additional daylight visibility. Each sight undergoes CNC machining from aircraft-grade aluminum for dimensional accuracy that matches factory specifications.

Key Features

• Green tritium front sight with yellow tritium rear for rapid target acquisition
• White outline rear sight enhances daylight shooting performance
• Self-illuminating tritium maintains brightness for 12+ years
• CNC-machined aluminum construction with corrosion-resistant finish
• Direct replacement for factory Glock sights - no gunsmith required
• Compatible with Glock 17, 17L, 19, 22, and 23 models
• Meets military specification standards for shock and vibration resistance

Field performance remains consistent across temperature extremes from -40°F to 160°F. The tritium illumination provides clear sight picture in complete darkness, dawn/dusk conditions, and indoor environments where lighting may be compromised. Law enforcement agencies rely on this sight configuration for duty weapons due to the instant sight alignment and all-weather reliability.
