AmeriGlo GL5301 i-Dot Sight Set for Glock - Black | Green Tritium Front Sight with Lumigreen Outline & Green Tritium i-Dot Rear Sight

The AmeriGlo GL5301 i-Dot sight set for Glock puts reliable night shooting in your hands without batteries or electronic components. This night sight pair is built for Gen 5 Glock pistols in 9mm and .40 S&W, pairing a green tritium front sight with a distinctive lumigreen outline against a green tritium rear sight marked with the trademark i-dot reference point. Whether you're training after dark, responding to low-light scenarios, or simply want iron sights you can trust when the sun goes down, these sights are designed to be fast on target and dead accurate in conditions where standard sights fail.

AmeriGlo's tritium technology is combat-proven: the green lamps glow without electricity, staying visible in near-total darkness for years. The lumigreen outline on the front sight gives you a defined aiming reference even in dim light without sacrificing the glow—you get both brightness and precision in one package. The i-dot rear sight uses a single green dot for fast target acquisition, cutting visual clutter and simplifying your sight picture under stress. The black matte finish keeps glint out of the equation and looks at home on any duty or tactical setup.

These are drop-in replacements for Gen 5 Glocks; installation is straightforward using Glock's dovetail system. If you shoot a 9mm or .40 pistol and want to extend your shooting day beyond daylight, this sight set delivers the reliability of proven tritium technology in a sight picture that rewards precision and speed alike.

Frequently Asked Questions

What Glock models do these sights fit?

The AmeriGlo GL5301 is designed for Glock Gen 5 pistols chambered in 9mm and .40 S&W. Gen 5 Glocks use the standard dovetail sight system, and these sights are a direct fit for that slot.

How long does the tritium stay bright?

Tritium is self-illuminating and requires no batteries or external power source. The brightness will gradually diminish over many years, but these sights will remain functional for an extended period. The lumigreen outline on the front sight also helps maintain visibility as tritium ages.

Are these sights fast to aim with?

Yes. The i-dot rear sight uses a single green dot instead of traditional three-dot geometry, which simplifies your sight picture and can speed up target acquisition, especially in low light or under stress. The bright front post stands out clearly against most backgrounds.

What's included in this set?

This is a complete sight set including both the front and rear sights needed to replace your factory Glock sights. Installation requires only basic tools and Glock's standard sight removal/installation technique.
