AmeriGlo's i-Dot sights use a dot over dot configuration. It features a single green dot Tritium front sight with a white outline (.125" wide), and a green single dot Tritium (no outline) with a .180" squared rear notch. The rear extends to end of slide for an increased sight radius and has an under-cut face to eliminate glare. AmeriGlo sights are machined from US-made bar stock steels and assembled using Swiss-made Tritium light sources.
