AmeriGlo GL102 i-Dot Night Sight Set for Glock 20/21/29/30/31/32/36 - Green Tritium White Outline Front / Green Tritium Rear

The AmeriGlo GL102 is an i-Dot night sight set for Glock pistols, using a fast dot-over-dot configuration that makes vertical sight alignment quick and intuitive. The set pairs a single green Tritium front sight with a white outline (0.125" wide) to a green Tritium rear sight with a single dot in a 0.180" squared notch, giving you a clear, battery-free aiming picture in low light.

Both components are machined from US-made bar stock steel with a black finish and assembled with Swiss-made Tritium light sources. The rear sight extends to the end of the slide for an increased sight radius, and the under-cut face eliminates glare for a cleaner sight picture.

The GL102 fits the Glock 20, 21, 29, 30, 31, 32, and 36 (Gen 1-4) chambered in 10mm Auto, .45 ACP, and .357 SIG. Whether you carry a Glock 20 for duty, run a Glock 21 at the range, or keep a subcompact 30 or 36 for personal defense, this set gives you a reliable aiming system that works day or night.
