Description
The AmeriGlo GL481 is a 2XL tall sight set made for Glock owners running a red dot, a suppressor, or both. When you mount a miniature optic on a MOS or milled slide, standard-height factory sights disappear behind the glass. This set raises your irons up to a lower 1/3 co-witness so you keep a usable aiming reference through the window, and the extra height clears most pistol suppressor profiles too. If your optic ever goes dark, you have real backup sights sitting right there ready to go.
What Sets the GL481 Apart
Up front you get a green tritium lamp wrapped in a bright white outline, measuring .350 inches tall by .125 inches wide. That white ring pulls your eye to the front post fast in daylight, while the tritium keeps it glowing in low light without needing batteries or a charge. The rear is a flat black .429-inch sight with no distracting dots, which keeps your focus where it belongs and cuts down on glare. It is a proven front-focus setup that a lot of serious pistol owners prefer.
Fit and Build of the GL481 Sight Set
These are machined from steel, so they hold up to hard use and repeated draws from a holster. The set drops into standard Glock dovetails and works across Gen 1 through Gen 5 models, including popular guns like the G17, G19, G34, and G45. It is also built with the Glock MOS slide setup in mind, making it a natural pairing for optics running an RMR-style footprint.
Getting the Most From Your AmeriGlo 2XL Sights
Installation is straightforward with a proper sight pusher, and the front typically secures with a hex screw. If you are pairing these with a specific optic, it is worth confirming your dot's deck height to dial in exactly how much of your co-witness you want. For most red dot and suppressor setups on a Glock, this 2XL height hits that sweet spot between too short to see and too tall to feel natural.

Frequently Asked Questions
Will the AmeriGlo GL481 co-witness with my red dot?
Yes, the 2XL tall height is designed to give you a lower 1/3 co-witness with most slide-mounted miniature red dots on a Glock MOS or milled slide. That means your irons stay visible in the lower portion of the optic window as a backup reference. For the tightest fit, check your optic's deck height, since RMR-footprint dots tend to line up best.
Does the GL481 work with a suppressor on my Glock?
It does. The taller .350-inch front and .429-inch rear are built to sit above most pistol suppressor profiles so your sight line clears the can. That is a big part of why these are called suppressor-height sights.
Which Glock models fit the GL481 sight set?
These fit standard Glock dovetails across Gen 1 through Gen 5, covering popular guns like the G17, G19, G34, and G45. They are also made with the MOS optic-cut slides in mind. Glock 42 and 43 models typically use different sights, so double-check your specific pistol before ordering.
Do the tritium sights need batteries?
No batteries required. The front sight uses a tritium lamp that glows on its own in low light and lasts for years, while the white outline helps you pick up the front post quickly in daylight. It is a true no-power night sight solution.
