When you cut a Glock slide for a red dot or thread a barrel for a can, the factory irons disappear below the optic glass. That's the whole problem the AmeriGlo GL813 solves. This XL Tall set raises both the front and rear sights up to suppressor height so they project into the bottom of your optic window, giving you a co-witness sight picture and a dependable fallback if the dot ever quits on you.
Both the front and rear feature green tritium inserts wrapped in a crisp black outline. That green glow does the heavy lifting after dark, while the blacked-out ring keeps the sight from washing out in daylight and cluttering up your red dot picture. The front sight measures .315 inches wide and the rear comes in at .394 inches, which puts your irons in that lower-third zone under the dot rather than stacking right on top of it. That's a setup most folks running a slide-mounted optic tend to prefer, since it keeps the reticle clean while still giving you a real sight picture in a pinch.
These are machined from steel with a matte black finish, so they hold up to holster wear, hard use, and years of carry without complaint. Tritium is self-powered and needs no batteries or charging, so the moment you draw in the dark, the dots are already lit. No fumbling, no wait.
The GL813 set drops into all Glock Gen 1 through Gen 5 models with the exception of the 42, 43, and 48. It's built to work alongside common optic footprints including the Aimpoint Acro, Holosun 509T, Steiner MPS, and Glock MOS slides. If you're pairing it with a red dot, match the height to your specific optic and mount so the co-witness lands where you want it. A little gunsmithing know-how or a sight pusher makes install painless, and plenty of shops will knock it out for you if you'd rather not tackle the rear dovetail yourself.
Yes, that's exactly what this set is built for. At .315 inches up front and .394 inches at the rear, the irons ride into the lower portion of most optic windows, giving you a lower-third style co-witness. Keep in mind that where the sights land depends on both the sight height and how tall your specific optic and mount sit, so match it to your dot for the best result.
The GL813 fits Glock Gen 1 through Gen 5 models with the exception of the 42, 43, and 48. It also works with MOS slides and pairs well with common optic footprints like the Aimpoint Acro, Holosun 509T, and Steiner MPS. If you've got an optic-cut slide, these are made to complement it.
No. The green tritium inserts are self-powered and glow on their own, so there's nothing to charge or replace. The instant you draw in a dark room or low light, the dots are already lit and ready. The black outlines keep them from washing out during the day, too.
You can, though the steel rear sight fits a tight dovetail and goes in easiest with a proper sight pusher rather than a punch. The front sight uses the standard Glock hex screw. If you'd rather not risk marring the slide, most gun shops will press these in for a small fee.
