AmeriGlo GL8113R Classic Tritium Rear Sight for Glock, Green 2-Dot

Description

The AmeriGlo GL8113R is a rear-only tritium night sight built for folks who want to upgrade a Glock without buying a whole new front sight to match. It runs a green tritium 2-dot layout with white outlines and a square notch, so you get a clean, familiar sight picture in daylight and glowing reference points once the sun goes down. At .256 inches tall with a .150 inch notch, it's cut for the standard Glock 17 and 19 pattern and drops into the factory dovetail.

What Sets the GL8113R Apart

This is machined from US bar-stock steel rather than the polymer that ships on most Glocks straight from the factory. That matters more than it sounds. A steel rear gives you a hard ledge you can catch on a belt or holster to rack the slide one-handed, and it shrugs off years of carry and holster wear. The Swiss-made tritium lamps are sealed inside, and AmeriGlo backs the glow for a long service life, so you're not looking at a replacement anytime soon.

Running the AmeriGlo Rear Sight as a Match or Standalone

Because it's the rear half only, this pairs naturally with an AmeriGlo Classic front, or you can run it alongside a brighter front like an orange or LumiGreen post if you want your eye pulled forward faster. The two rear dots frame your notch and let you confirm alignment in low light, while a lot of shooters like keeping a plainer, less busy rear so the front sight stays the star of the show.

Fit and Install Notes

Installation is straightforward with a rear sight pusher, and most Glock owners handle it at the bench without a gunsmith. The dovetail cut on these tends to run true, though a fresh slide occasionally wants a light tap to seat fully. Once it's in, you drift left or right to zero and you're set. It's a proven, no-drama upgrade for a duty gun, a nightstand pistol, or an everyday carry Glock that deserves better than factory plastic.
