Trijicon HD Tritium Sight Set Features The Trijicon HD Tritium Sight Set is built around a domed sapphire and tritium front sight that Trijicon rates as twice as bright as standard tritium sights helping shooters acquire the front sight faster under stress or low light. The orange photoluminescent outline on the front sight gathers ambient light during the day giving a highly visible reference point even before low-light conditions call on the tritium element itself. On the rear a green tritium insert with a black outline sits inside an angled serrated U notch that is specifically shaped to cut down glare and keep the shooter s focus locked on the front sight. This three-dot self-luminous configuration is the same design trusted by law enforcement and serious personal protection shooters worldwide. Machined from steel and finished in black this sight set is built to withstand the recoil and holster wear that a duty or carry pistol sees over its service life. It is fitted specifically for the Glock Large Frame family covering the 20 21 29 30 and 41 models along with their S and SF variants so installation is a direct drop-in upgrade. The set ships complete with a front sight rear sight and front sight mounting screw so no additional hardware sourcing is required. At just 0.42 ounces it adds essentially no weight while delivering a meaningful boost in sight acquisition speed and low-light performance.
