Running a micro red dot on your Glock 43X or 48 MOS is great until the battery dies or the dot blinks out at the worst possible moment. That's exactly what this AmeriGlo Optic-Compatible sight set is built for. It pairs a tall .220 inch serrated front blade with a flat black .295 inch rear notch, giving you an elevated sight picture that lines up right in the bottom of your optic window so you always have irons to fall back on.
The whole set is finished in flat black, and that's the point. There's no glowing front dot fighting your red dot for attention. The blacked-out design keeps your sight picture clean so your eye stays on the dot during normal shooting, then the irons are right there when you need them. Folks who have mounted these on a 43X or 48 with a Holosun and adapter plate consistently mention the finish and fit are dialed in, and that the height sits just high enough to be useful without crowding the optic's field of view.
This is a lower co-witness setup designed specifically around the K-footprint Holosun optics like the 407K and 507K when they're mounted on a MOS slide with the right adapter plate. Because co-witness height depends a lot on how thin your plate is, the general rule holds true here: a slim plate gets you the cleanest alignment. The front blade measures .115 inch wide with a square .150 inch rear notch, which gives you a clear, repeatable picture for both quick target work and slower, precise shots.
These are steel sights that press into the standard Glock dovetails, so a sight pusher makes the job painless. They're a set, meaning both front and rear come in the box. Whether the gun rides in a carry holster or just gets range time on the weekend, this is a straightforward, durable way to back up your dot without cluttering the sight window.
This set is built around the K-footprint Holosun optics, specifically the 407K and 507K, mounted on a Glock 43X or 48 MOS slide. You'll want a proper adapter plate for the K-footprint on your slide, and a slimmer plate generally gives you the cleanest lower co-witness. The elevated sight height is designed to line up in the bottom of the optic window as a reliable backup.
They physically press into the standard Glock dovetails, but the tall .220 inch front and .295 inch rear are meant for a slide running a red dot. On a non-optic gun the sight picture will sit high, so these really shine on a MOS slide with a Holosun mounted. If you're not running an optic, a standard-height set is the better call.
No, this version is all flat black on both the front and rear. That's intentional so nothing competes with your red dot during normal shooting. If you want a tritium or colored outline front, AmeriGlo offers other versions in the same optic-compatible lineup.
The GL-453 comes as a complete set with both the serrated front sight and the flat black rear sight in the box. AmeriGlo does also offer these components individually, but this SKU gets you the pair. A sight pusher tool makes installation quick and clean.
