The AmeriGlo i-Dot Night Sight Set (brand part no. GL101) uses a dot-over-dot configuration that gives shooters a quick, easy vertical sight alignment reference instead of the traditional three-dot pattern. The front sight carries a single green tritium dot inside a .125-inch-wide white outline for fast daylight acquisition, while the rear sight uses a single green tritium dot with no outline, set in a .180-inch squared notch that extends to the end of the slide for a longer, more precise sight radius. AmeriGlo builds this set for standard Glock Gen 1-4 models in 9mm, .40, and .380, as well as Gen 5 models in 10mm and .45, though it is not designed to fit an MOS-cut slide. It’s a genuine tritium night sight upgrade for a duty or carry Glock that needs fast, reliable low-light indexing.
