Night Fision Tritium Night Sights (brand part number GLK-001-014-YGZX) are built for the full-size Glock 17/17MOS/19/19MOS/22/23/26/27/33/34/35/37/38/39/42/43/43X/45/47/48 family, fitted with a green tritium front lamp inside a yellow outline and a plain black/blank rear for a clean, uncluttered reference. Night Fision carries more tritium than the average night sight, and its patented injection-molded sleeve, what the company calls The Perfect Dot, holds each vial securely for a brighter, more durable glow than a typical ring. A domed lens collimates the tritium light for a sharper sight picture, and the whole sight is CNC-machined from high-quality steel with a Black Nitride coating for wear and corrosion resistance. Built in the USA with Swiss tritium, gunsmith installation is recommended.
