The Meprolight USA 107763101 Tru-Dot Sight Set delivers consistent target acquisition in low-light conditions through self-illuminated tritium technology. This sight set transforms standard 1911 pistols into reliable 24-hour defensive tools without requiring batteries or external light sources.
What Makes This Different
Unlike standard white-dot sights that disappear in darkness, these tritium-powered sights maintain visibility for 12+ years through radioactive decay illumination. The green tritium provides optimal contrast against most backgrounds while remaining gentle on night-adapted vision. Each sight undergoes precision CNC machining to ensure proper sight alignment and consistent point-of-impact.
Key Features
- Self-illuminated green tritium inserts rated for 12+ year lifespan
- CNC-machined steel construction with corrosion-resistant finish
- Direct replacement for factory Colt 1911 Government and Commander sights
- Three-dot configuration with front and rear tritium illumination
- No-gunsmithing installation using standard sight pusher tools
- Maintains factory sight height for existing holster compatibility
- Shock-resistant design rated for +P ammunition
Field testing demonstrates reliable illumination in complete darkness while maintaining precision during daylight shooting. The sight set performs consistently across temperature extremes from -40°F to 160°F. Competition shooters report improved split times during low-light stages, while law enforcement agencies document enhanced target identification capabilities during dawn and dusk operations.
