Description
The AmeriGlo GL115 is a proven upgrade over factory Glock sights, swapping out the stock plastic for a full steel set that glows on its own. The green tritium front dot sits between two yellow tritium rear dots, and each lamp is wrapped in a crisp white outline so you get a clean 3-dot picture whether you're on a bright range or in a dark hallway. No batteries, no switches, no charging. The tritium does the work around the clock.
Why the GL115 Classic Setup Works
AmeriGlo built the Classic series around the layout that personal defense, law enforcement, and military folks have relied on for years. The front blade runs .140 inches wide with a .150 inch rear notch, which gives you enough light on either side of the front post for quick, instinctive alignment. Running different colors front and rear is a deliberate choice. It helps your eye lock onto the green front dot fast under stress, which is exactly what you want when the lighting isn't ideal.
Built From Steel With Swiss Tritium
These sights are CNC machined from steel and fitted with Swiss-made tritium vials, so they hold up to slide cycling and years of carry. The white outline rings are a big part of the appeal. During daylight they read like standard high-visibility sights, and once the sun drops the tritium takes over. That dual-purpose visibility is why so many people put these on a nightstand gun or an everyday carry piece.
Glock Fitment for the AmeriGlo GL115
This set is cut for Gen 1 through 4 Glock models including the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. The front sight screws into the slide from underneath, while the rear seats into the dovetail. AmeriGlo rear sights tend to run tight, which is a good thing for retention, though a sight pusher makes the job cleaner and safer for the vials than tapping them in by hand.

Frequently Asked Questions
What Glock models does the AmeriGlo GL115 fit?
The GL115 is cut for Gen 1 through 4 Glocks, including the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. It is not made for MOS or Gen 5 models. Always confirm your slide cut before installing.
Do these sights need batteries to glow?
No. The GL115 uses self-luminous Swiss-made tritium vials that glow on their own with no batteries or charging required. The tritium provides low-light visibility around the clock, and the vials stay usable for years.
Why is the front dot green and the rear dots yellow?
The two-color setup is intentional. Having a green front dot against yellow rear dots helps your eye pick up the front sight faster under stress or in dim light, which is the sight most important for accurate shooting. Many people find this speeds up target acquisition compared to a matching 3-dot layout.
Can I install the GL115 myself?
Yes, though the right tools make a big difference. The front sight screws into the slide from below, and the rear seats into the dovetail. AmeriGlo rear sights run on the tight side, so a sight pusher is strongly recommended over a hammer and punch to protect the tritium vials during install.
