The AmeriGlo GL-112-180 is a tritium front night sight designed to replace the plastic factory front post on your Glock. It runs a green tritium vial ringed by a crisp white outline, so you get a fast, easy sight picture in broad daylight and a self-illuminating glow when things get dark. At .180 tall and .140 wide, this is one of the more common heights AmeriGlo offers, and it drops into the front dovetail on Glock slides.
Tritium is the big draw here. Unlike fiber optic or painted dots, tritium glows on its own around the clock with no batteries and no need to charge it under a light. That makes this style of sight a favorite for carry guns and home-defense setups where you might have to aim in the dark. Tritium runs on a long half-life, so expect years of dependable glow before it starts to dim. The white outline earns its keep during the day by giving your eye something bright and high-contrast to grab onto fast.
This is a front sight only, not a full front-and-rear set, so plan on pairing it with a rear sight that matches your intended sight picture and height. Installation is a straightforward job for anyone comfortable working on their own pistol. The Glock front sight is held on by a hex nut threaded in from underneath the slide, and it uses a 3/16 driver or a dedicated Glock front sight tool. A dab of blue threadlocker keeps the nut from backing out under recoil. Take it slow when you snug it down since over-tightening can crack the tritium vial, and always confirm your firearm is unloaded before you start.
AmeriGlo has a solid reputation for building reliable defensive sights, and this front post is a proven, no-nonsense way to make your Glock easier to run in low light without breaking the bank.
Yes, AmeriGlo lists this front sight as fitting all Glock models. It seats in the standard Glock front dovetail. That said, always verify the .180 height works with the rear sight and sight picture you're running before you commit.
This is the front sight only. You'll want to pair it with a rear sight that matches your preferred setup and height. Many folks run an AmeriGlo or blacked-out rear with a bright front like this one for a fast pick-up in low light.
The Glock front sight is held on by a hex nut that threads in from the underside of the slide. A 3/16 driver or a dedicated Glock front sight tool does the job. A drop of blue threadlocker keeps it from loosening under recoil, and go easy on the final turn so you don't crack the tritium vial.
Tritium has a roughly 10-year half-life, so it glows on its own for years without any batteries or charging. Over time it gradually dims rather than shutting off suddenly. When the glow starts fading noticeably, that's your cue it's time for a fresh sight.
