The ATI 3-Dot Tritium Night Sights (brand part number ATINSGLOLF) give a Glock large-frame pistol a low-light sight picture that doesn’t rely on ambient light or a weapon light to find. American Tactical builds the set around green tritium inserts ringed in white outlines, front and rear, so the shooter gets a fast, high-contrast 3-dot picture in daylight and a glowing reference in the dark. Sized specifically for Glock large-frame models, it’s a direct-fit upgrade for a duty or home-defense pistol that needs to be usable the moment the lights go out.
