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 yellow photoluminescent outline on the front sight gathers ambient light during the day giving a highly visible daytime reference before tritium takes over in low light. On the rear a green tritium insert with a black outline sits inside an angled serrated U notch shaped specifically 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 concealed carry or duty pistol sees over its service life. It is fitted specifically for the compact Glock 42 43 43X 43X MOS 48 and 48 MOS family so installation is a direct drop-in upgrade for smaller-frame carry guns. 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.
