The AmeriGlo GL301 i-Dot sight set transforms standard Glock pistols into reliable low-light performers with self-illuminating tritium inserts. This configuration pairs a green tritium front sight with bright LumiGreen outline against a green tritium rear sight for rapid target acquisition in any lighting condition.
What Makes This Different
Unlike basic white dot sights that disappear in darkness, the GL301 system uses Swiss tritium gas tubes that glow continuously for 12+ years without batteries or external light sources. The front sight combines tritium illumination with a photoluminescent LumiGreen outline that charges from ambient light and glows brightly when transitioning from light to dark environments. This dual-illumination approach provides faster sight acquisition than tritium-only configurations.
Key Features
- Swiss tritium inserts rated for 12+ year continuous illumination
- LumiGreen photoluminescent outline on front sight for enhanced visibility
- Machined steel construction with nitride finish for corrosion resistance
- Standard Glock dovetail dimensions - no gunsmithing required
- Green tritium rear sight with white outline for consistent sight picture
- Compatible with most Glock holsters and sight covers
- i-Dot configuration eliminates front/rear sight confusion in stress
The GL301 system excels in tactical and defensive applications where lighting conditions change rapidly. Law enforcement officers report faster target acquisition during building searches and vehicle stops. The green tritium provides sufficient illumination for precision shooting at typical defensive distances while the LumiGreen outline ensures the front sight remains visible during daylight transitions. The steel construction withstands repeated holstering and environmental exposure without losing zero.
