When you cut your Glock slide for a red dot, your factory sights disappear under the optic window. That's where the AmeriGlo GL-809 comes in. This XL height set sits tall enough to give you a proper co-witness through most slide-mounted mini red dots, so you always have a reference even if the electronics go dark. It's built for the Aimpoint Acro, Holosun 509T, Steiner MPS, and similar footprints riding on a Gen4 or Gen5 MOS slide.
The front sight runs a green tritium vial ringed in a black outline. That combo is the sweet spot for a lot of people: the tritium keeps you lit up in low light without any batteries, while the black ring gives you a crisp, high-contrast dot in daylight instead of a washed-out glowing blob. The rear is a flat black, case-hardened blade with a square notch, which keeps your eye off the rear and lets you drive to the front dot fast.
This is the .315 inch front and .394 inch rear XL configuration. Both blades are machined steel with a case-hardened finish, the front blade is .125 inch wide, and the rear notch runs .15 inch. That's a comfortable amount of light on either side of the front post, which is a nice balance between precise slow-fire shots and fast target transitions on the clock.
The GL-809 covers all Glock generations 1 through 5 except the 42 and 43. Whether you're running a 17, 19, 34, or a 45, this set drops into the standard sight dovetails. Just keep in mind these are tall suppressor and optic height sights, so they're really meant to co-witness with a red dot or clear a can. If you're running irons only, you'll want a standard height set instead. AmeriGlo sights get used all over by law enforcement, military, and folks who just want their carry or competition gun set up right.
Yes, that's exactly what this XL height set is built for. These sights are tall enough to give you a co-witness sight picture through most slide-mounted mini red dots like the Aimpoint Acro, Holosun 509T, and Steiner MPS on a MOS slide. They also serve as reliable backup irons if your optic ever goes down.
The GL-809 fits all Glock models across generations 1 through 5, with the exception of the 42 and 43. It drops into the standard front and rear sight dovetails, so a 17, 19, 34, 45, and similar models are all covered. Since these are tall optic height sights, they're best paired with a red dot or suppressor rather than run as standalone irons.
No batteries required. The front sight uses a self-illuminating green tritium vial that glows on its own in low light and lasts for years. The black outline around the front dot also gives you strong contrast in daylight, so you get a usable sight picture in any lighting.
Front and rear sights press into the Glock dovetails, and most people use a sight pusher or take the slide to a gunsmith for a clean install. The rear can sometimes be tapped in with a proper punch and brass, but a pusher makes windage adjustment much easier and avoids marring the finish. Threadlock on the front sight screw is a good idea to keep it locked in place.
