The Night Fision Tritium Night Sights (brand part number GLK002007YGW) fit the large-frame Glock 20, 21, 29, 30, 36, 40, and 41, including S and SF variants, with a green tritium front sight in a yellow outline and a matching green tritium rear in a white outline. Night Fision packs more tritium into each vial than the average night sight and uses a domed lens to collimate the tritium rays into a crisp, defined glow it calls The Perfect Dot, engineered with a patented injection-molded sleeve that holds the vials securely and resists fading. Each sight is CNC machined from high-quality steel and finished in black nitride for wear and corrosion resistance. Because the sights are pressed into a dovetail, Night Fision recommends a gunsmith perform the installation to avoid damaging the slide.
