The AmeriGlo GL8113R Classic Tritium Rear Sight for Glock delivers always-on, passive illumination for faster target acquisition in low-light conditions—exactly what you need for defensive carry, home defense, or night shooting drills. This is a self-illuminating Tritium sight, meaning it glows in darkness without batteries or activation, a proven design trusted by shooters who demand reliability when it matters most. The green Tritium 2-dot configuration paired with white outline creates a high-contrast sight picture that's easy to pick up quickly, whether you're indexing in daylight or responding in dim environments.
Designed to fit all Glock pistol models, the GL8113R is engineered for drop-in installation without gunsmithing. The .276" height and .165" square notch dimensions are purpose-built for Glock's standard dovetail cut, so you get a secure, factory-feel fit. The combination of green Tritium dots and white outline maximizes visibility across lighting conditions while maintaining the classic Glock sight profile that shooters know and prefer.
AmeriGlo Tritium sights are built tough for everyday carry and frequent use. If you're upgrading from factory Glock plastic sights or looking for reliable night-sight performance on a duty or carry gun, the GL8113R delivers the low-maintenance illumination and speed you're after without asking you to retrain your natural sight picture.

Frequently Asked Questions
Will the GL8113R fit my Glock pistol?
Yes, the AmeriGlo GL8113R is designed to fit all Glock models. It installs into the standard Glock dovetail cut and requires no gunsmithing.
How does green Tritium sight illumination work?
Tritium is a radioactive isotope that glows continuously in darkness without batteries, activation, or charging. The green Tritium dots will be visible in low-light and nighttime conditions for the life of the sight, making it ideal for defensive and carry applications.
What does the white outline do?
The white outline around the Tritium dots increases contrast and visibility in daylight and bright conditions, helping you acquire the sight picture quickly across a wider range of lighting environments.
Can I install this myself?
The GL8113R is a direct dovetail fit for Glock pistols. Many shooters install Glock sights themselves, though gunsmith installation is always an option if you prefer professional fitting.
