Description
The AmeriGlo GL125 Ghost Ring Sight Set takes a different approach than the three-dot setup most Glocks ship with. Instead of lining up a front post inside a rear notch, you get a large aperture rear ring with two green tritium mini-dots and a bright green tritium front with a white outline. Focus on the front, and your eye drops it right into the center of the ring without much conscious thought. That natural centering is the whole point, and it tends to happen faster than juggling three separate reference points under pressure.
What Makes the GL125 Ghost Ring Different
The ghost ring style has a loyal following for good reason. Folks running bifocals or dealing with aging eyes often find the big rear aperture easier to work with, and it shines for quick front-sight acquisition. Shooting with both eyes open feels natural, and the setup is popular with anyone who wants an alternative to the standard post-and-notch picture. It's a design borrowed from the rifle and shotgun world that translates surprisingly well to a defensive pistol.
Built to Take a Beating
AmeriGlo doesn't cut corners on the hardware. The GL125 is CNC machined from US steel bar stock and finished in matte black, with Swiss-made tritium light sources handling the glow. The rear sits on a friction fit with an angled, undercut face that helps cut down on glare in bright conditions. These sights get used worldwide by law enforcement, military, and everyday defense-minded folks, so they've earned their reputation the hard way.
Fitment for Your Glock GL125 Set
This set covers a wide swath of Gen 1 through Gen 4 Glocks, including the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. It's a two-piece front and rear set that installs with standard tools, though you'll want a sight pusher for the dovetail and the AmeriGlo GTool for the rear screw. Note that it isn't cut for MOS slides, so if your Glock has the optics cutout, you'll want to look at a set made for that platform.

Frequently Asked Questions
What Glock models does the AmeriGlo GL125 fit?
The GL125 is made for Gen 1 through Gen 4 Glocks, covering the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. It is not cut for MOS slides with the optics cutout, so those models need a different set. If you run a full-size or compact Glock in 9mm or .40 from those generations, you're in good shape.
How does a ghost ring sight compare to standard three-dot sights?
Instead of aligning a front post inside a rear notch, you focus on the front sight and let your eye center it naturally inside the large rear aperture. Many find this faster and more intuitive, especially shooting with both eyes open. It's a favorite for folks with aging eyes or bifocals who struggle to keep three separate references in focus.
Do the GL125 sights use night sights, and how long does tritium last?
Yes, both the front and the two rear dots use Swiss-made tritium that glows on its own with no batteries or charging needed. Tritium is self-luminous and typically stays usable for well over a decade before it noticeably dims. The green front with its white outline also gives you a clear reference in daylight.
What do I need to install the AmeriGlo GL125?
You'll want a sight pusher tool to move the front and rear sights in the dovetail, since they're a tight friction fit. The AmeriGlo GTool works as a nut driver for the rear sight screw and is not included. If you're not comfortable doing it yourself, most gunsmiths can knock out the install quickly.
