The AmeriGlo GL101 i-Dot swaps out those plain factory Glock sights for a tritium setup that stays visible whether you're at the range at noon or clearing a dark hallway at 2 a.m. The front sight uses a green tritium lamp wrapped in a bright white outline so your eye snaps right to it, while the rear carries a single green tritium dot below a wide .180-inch square notch. Stack the front dot over the rear dot, line up the notch, and you've got your shot. That simplicity is the whole point of the i-Dot design.
Instead of the usual three-dot picture, this set runs a dot-over-dot configuration that makes vertical alignment quick and natural, which is a big help when the light drops and speed matters. The rear sight extends to the end of the slide for a longer sight radius, and the face is undercut to cut down on glare bouncing back at you. Tritium does the illumination work on its own, so there are no batteries, switches, or charging involved. It just glows.
AmeriGlo machines these from US-made bar stock steel and assembles them with Swiss-made tritium lamps, so they hold up to daily carry, hard use, and years of holster wear. The blacked-out frame keeps glare down and blends cleanly with a stock Glock slide. Folks who run these tend to praise how clean the sight picture is and how well it works for their eyes in dim conditions.
This set covers a wide swath of the Glock lineup, including the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. It's cut for Gen 1-4 models in 9mm, .40, and .380, plus Gen 5 pistols in 10mm and .45. One thing to know up front: these do not fit Glock MOS slides. Installation is straightforward with a front sight tool and a rear sight pusher, and plenty of owners knock it out at home in a few minutes.
No, this set is not cut for Glock MOS slides. It's designed for standard Gen 1-4 slides in 9mm, .40, and .380, along with Gen 5 models in 10mm and .45. If you're running an MOS slide with an optic cut, you'll want to look at AmeriGlo's optic-compatible height sights instead.
The i-Dot uses a single dot on the front and a single dot on the rear, so you stack one dot over the other rather than lining up three across. That vertical dot-over-dot picture is quick to pick up and cuts down on the visual clutter you get with three dots, especially in low light.
Not at all. Tritium glows on its own through a self-contained reaction, so there's nothing to charge, switch on, or replace. The lamps stay lit around the clock, which is exactly what you want on a defensive or carry pistol.
Most people can. The front sight comes off with a Glock front sight tool, and the rear seats in the dovetail with a sight pusher or brass punch. Plenty of owners report getting the swap done at home in just a few minutes, though a gunsmith can handle it fast if you'd rather not.
