Description
The AmeriGlo GL-806 is a tall, optic-compatible sight set built for the slim Glock family, fitting the Glock 42, 43, 43X, and 48 including MOS slides. It runs green tritium up front and a matching green tritium single dot in the rear, both wrapped in black outlines that keep things clean and glare-free in bright light. The extra height is the whole point here. These sit taller than factory irons so you get a lower-third or absolute co-witness through most slide-mounted red dots, and they double as reliable back-up sights if your optic ever goes dark.
What the GL-806 Brings to Your Slide
The front blade measures .220 inches with a .295 inch overall rear height, giving you that raised sight plane that lines up with popular micro red dots. The rear features a square notch and a flat black finish, which cuts down on reflection and pushes your eye toward the front dot where it belongs. Tritium in both the front and rear means the aiming reference glows on its own in low light without needing to charge up under a flashlight first.
Installing the GL-806 Sight Set
Like most Glock sights, these press into the dovetails and a sight pusher tool makes the job painless. Plenty of folks handle it at home with the right tool and a front sight nut driver, though a gunsmith can knock it out fast if you would rather not fuss with it. Once they are set and zeroed, you are good to go.
AmeriGlo has been a go-to name for aftermarket handgun sights for years, known for steel construction and tritium lamps that hold up to real carry and range use. If you have added a red dot to your slim Glock and need irons that actually work with it, or you just want a brighter, taller reference than the stock plastic sights, the GL-806 is a solid pick that covers both jobs at once.

Frequently Asked Questions
What Glock models does the AmeriGlo GL-806 fit?
The GL-806 is made for the slim Glock lineup, covering the Glock 42, 43, 43X, and 48, including MOS slides. These are the smaller single-stack and slimline frames rather than the wider Glock 19 or 17 pattern. Always confirm your exact model before ordering.
Will the GL-806 co-witness with a red dot on my Glock?
Yes, that is the main reason these exist. The L tall height raises the sight plane so it lines up with most slide-mounted micro red dots for a co-witness, and the tritium lamps make them dependable back-up sights if your optic loses power. Co-witness height can vary a little depending on your specific optic, so check your dot's mounting height.
Are the AmeriGlo GL-806 sights tritium front and rear?
They are. The front features a green tritium lamp with a black outline, and the rear carries a green tritium single dot, also with a black outline and flat black finish. That gives you a self-illuminating aiming reference in low light without needing to charge them under a light first.
Do I need special tools to install the GL-806?
A sight pusher tool makes installing these into the Glock dovetails simple, and you will want a front sight nut driver for the front blade. Many people install them at home with the right tools, but a gunsmith can handle it quickly if you prefer. Either way, plan to re-zero after the swap.
