Description
The AmeriGlo GL470 is a 2XL tall sight set made for one job: giving optic-equipped and suppressed Glocks a proper set of irons that sit high enough to actually be useful. With a .350 front and .429 rear, these blades ride tall enough to peek through your red dot window or clear the top of a can, so you always have a backup sight plane when you need it. It's steel, it's all business, and it's finished in a clean matte black.
What the GL470 Height Actually Gets You
Height is everything with suppressor and optic sights, and this is where the 2XL profile earns its keep. Depending on your optic and mounting setup, the GL470 gives you a lower 1/6 co-witness with RMR-footprint optics like the Trijicon RMR, Holosun 407C, 507C, and 508T, and steps up to a lower 1/3 co-witness with taller optics like the Aimpoint ACRO P2 and Holosun 509T. That means your dot and your irons line up in the same window, so if the electronics ever quit on you, you're not scrambling to find a sight picture.
Sight Picture and Build on the GL470
This is an all-black set, front and rear. The front blade is serrated to knock down glare in bright light, and the flat black rear keeps the whole picture clean and uncluttered, which pushes your eye toward front-sight focus or the dot without distraction. Both are cut from steel, so they'll hold up to a sight pusher on install and years of holster wear after that. Folks who run these on RMR-equipped Glocks tend to mention how thin and easy the front blade is to pick up through the glass.
Fit for Your Optic-Compatible Glock Setup
The GL470 fits nearly all Glock Gen 1-5 models, including MOS slides, with the notable exception of the slim 42 and 43. It's also built to the Vortex Viper footprint. If you're setting up a red-dot duty gun, a suppressed range toy, or just want dependable backup irons behind your optic, this is a straightforward, proven choice. A sight pusher makes installation clean, and many find no fitting is needed to get the rear seated.

Frequently Asked Questions
Will the AmeriGlo GL470 co-witness with my red dot?
Yes, that's exactly what the 2XL height is built for. You'll get roughly a lower 1/6 co-witness with RMR-footprint optics like the Trijicon RMR, Holosun 407C, 507C, and 508T, and closer to a lower 1/3 co-witness with taller optics such as the Aimpoint ACRO P2 and Holosun 509T. Exact height can shift slightly depending on your slide and mounting plate.
Does the GL470 have tritium night sight inserts?
No, this is an all-black set with a serrated front and flat black rear. It's designed as a clean, glare-free backup and co-witness sight rather than a glowing night sight. If you want tritium, AmeriGlo offers other optic-compatible sets in the same height family.
Which Glocks does the GL470 fit?
It fits most Glock Gen 1 through Gen 5 pistols, including MOS-cut slides. The main exceptions are the slim single-stack Glock 42 and 43, which use a different sight cut. It's also cut to the Vortex Viper footprint.
Is the GL470 hard to install?
It's a standard Glock sight install. A sight pusher is the right tool for both the front and rear, and many users report the rear slides in cleanly with no fitting required. If you're not comfortable pressing your own sights, most gun shops can knock this out in a few minutes.
