The TRIJICON HD FOR GLK MOS 9MM YLW from Trijicon is designed to enhance tactical handgun performance with a three dot green tritium night sight set for Glock MOS platforms, including models 17MOS, 19MOS, 34MOS and more. The front sight features a taller blade and an aiming point ringed in photoluminescent paint, while the rear sight is outlined in black with a wider U-shaped notch, a combination that improves visibility and speeds front sight acquisition in transitional lighting conditions. A steeply hooked front surface on the rear sight also aids emergency one?handed slide operation, making it a practical choice for duty, competition, or personal defense scenarios. The green tritium lamps are rated to provide reliable visibility for years, backed by a 12?year warranty from the date of manufacture. Built with a matte finish and a Yellow Outline accent for quick recognition, these sights are compatible with Glock MOS configurations and are designed to deliver fast, repeatable sight picture in varied environments without sacrificing precision. Whether refining a duty rig or enhancing a hunting pistol, the HD sights offer robust performance, quick target acquisition, and durable, long?lasting illumination.
