Description
The AmeriGlo GL-112-200 is a single front night sight built to replace the factory front post on your Glock. It pairs a green tritium lamp with a white painted outline, so you get a glowing dot when the lights go out and a high-contrast ring to draw your eye during the day. AmeriGlo has been making Glock front sights for a long time, and this Classic Tritium series is one of the most widely used front sights out there for good reason.
What Sets the GL-112-200 Front Sight Apart
The body is machined steel with a case-hardened finish that shrugs off holster wear and keeps glare down for a clean sight picture. This specific model runs a .200 inch blade height and a .140 inch blade width, which is a common combo that works well with a variety of rear sights. It fits all Glock models that use the standard oval front sight cut, so whether you are running a 17, 19, 26, 34 or something in between, the base seats into the slide the same way.
Getting the Most From Your Green Tritium Front Sight
Tritium glows on its own without any charging from a light source, which is what makes it so handy for a carry or home-defense pistol. The green lamp is the brightest color to the human eye, so it reads fast in the dark and holds up well over the years. Pairing this front with a matching AmeriGlo rear gives you a proper night sight setup and a consistent picture in just about any lighting.
A Few Notes on Installing the GL-112-200
This is a front sight only, and it uses a hex screw that threads up through the slide. Installation calls for the correct AmeriGlo front sight tool and a small dab of blue thread locker on the screw to keep it from backing out at the range. If you are not comfortable pulling your slide apart, any gunsmith can swap it in quickly.

Frequently Asked Questions
Does the GL-112-200 fit my Glock?
Yes, this front sight is cut to fit all standard Glock models that use the factory oval front sight slot. That covers popular guns like the 17, 19, 22, 23, 26, 34 and many others. The base seats into the slide the same way across the lineup, so you are not locked into one specific model.
Is this a full sight set or just the front sight?
This is a front sight only. It replaces the factory front post but does not include a rear sight. If you want a complete night sight picture, pair it with a matching AmeriGlo rear so the front and rear work together.
What do the .200 and .140 measurements mean?
Those numbers are the blade height and blade width of the sight. This model runs a .200 inch height and a .140 inch width, which is a common size that pairs well with a range of rear sights. Height matters for zeroing, so match it up with your rear sight and load if you have a preference.
How long does the tritium stay bright?
Tritium glows on its own and does not need light to charge, which makes it great for a carry or nightstand gun. The green lamp will stay usefully bright for many years before it slowly dims. Green is also the easiest color for the human eye to pick up in the dark.
