The AmeriGlo GL-880 is a sight set built for the way people run Glocks now: with a micro red dot up top. It pairs a 1L tall green tritium front sight wearing a clean black outline with a flat black rear cut in a square notch. That extra height raises the sight picture just enough to co-witness through your optic window, so if the dot ever goes dark you already know exactly where your irons are.
Running a slide-mounted optic and want backups that line up with it, this is the combo. The .220 inch front and .295 inch rear give you a lower 1/3 co-witness on a Glock 43X or 48 MOS paired with a Holosun 407K, 507K, or EPS Carry, which is one of the more popular micro red dot footprints out there. The green tritium front lamp lights up on its own in the dark, no batteries or charging, so your front reference is always there whether the electronics are on or off.
The black outline around the front lamp keeps things clean in daylight and lets your eye snap right to the glowing center when the lights drop. The rear stays flat black with no distracting dots, which pushes all your focus onto that front sight the way a good defensive setup should. Everything is steel, so it holds up to holster wear, hard use, and repeated draws.
These seat in the standard Glock dovetail and are meant to be pressed in with a proper sight pusher, front sight tool, and a drop of thread locker on the front screw. If you don't have the tools on hand, any gunsmith or shop counter can knock the install out in a few minutes and confirm your co-witness lines up right with your optic. Take a look and get your backup irons dialed in before your next range trip.
The 1L tall height is set up for a lower 1/3 co-witness on a Glock 43X or 48 MOS running a micro red dot in the Holosun 407K, 507K, or EPS Carry footprint. That means your irons sit low in the optic window so the dot stays the primary reference while the tritium front is right there as a backup. If you run a different optic or slide, check its window height against the .220 inch front to confirm the co-witness works for you.
No. The green tritium front lamp is self-powered and lights up on its own in low light, no batteries or charging required. Tritium naturally dims over many years, but you get a long service life of always-on visibility in the dark.
It seats in the standard Glock dovetail and is designed around the MOS 42, 43, 43X, and 48 models, and AmeriGlo lists it as fitting additional Glock models as well. Since fitment can vary by generation and slide cut, it's worth confirming your exact model and optic before installing. Any shop counter can help you match it up.
You can if you have the right tools. A Glock sight pusher for the rear, a front sight tool for the front screw, and a dab of thread locker will get the job done. If you'd rather not chance it, a gunsmith can press them in and verify your co-witness in just a few minutes.
