The AmeriGlo GL101 i-Dot sight set for Glock pistols pairs a tritium front sight with a tritium rear sight to give you fast, reliable target acquisition in low light and daylight alike. The front sight features a white outline around the tritium lamp, making it easier to pick up quickly, while the rear sight uses AmeriGlo's i-Dot design with green tritium for intuitive sight picture alignment. This combination is built for shooters who want self-illuminating sights without breaking their sight picture or spending time hunting for sight reference in dim conditions.
AmeriGlo sights are purpose-built for Glock pistols, so fit and function are tuned specifically to your platform. Whether you're training at the range, carrying for self-defense, or shooting in variable light, tritium sights keep you pointed downrange when you need it most. The green tritium on both front and rear creates a cohesive, easy-to-use sight picture that works naturally with how your eyes perceive movement and alignment.
Installation requires basic gunsmithing or professional fitting—these sights replace your factory Glock sights. Once installed, they require no battery, charging, or calibration. The tritium will stay visible for years, giving you dependable illumination through the life of your pistol.

Frequently Asked Questions
Will the AmeriGlo GL101 fit my Glock?
Yes—the GL101 is designed specifically for Glock pistols. These sights are drop-in replacements for your factory Glock sights, though professional installation is recommended for best results.
How long does the tritium stay visible?
Tritium is self-illuminating and requires no charging or batteries. The lamp brightness will naturally decrease over time (typically several years), but the sights remain usable throughout their lifespan.
What's the difference between the front and rear sights in this set?
The front sight uses green tritium with a white outline to make it faster to acquire, while the rear sight features AmeriGlo's i-Dot design with green tritium for sight picture alignment. Both use a .180" wide profile.
Can I use these sights for low-light shooting?
Yes. Tritium sights are specifically designed for low-light and night shooting situations where traditional iron sights become hard to see. The self-illuminating tritium lamp keeps your sights visible without requiring any external light source.
