The Trijicon DI Night Sight Set (brand part number 601106) brings Trijicon’s dual-illumination (DI) technology to the Glock 42, 43, 43X, and 48, excluding MOS-cut models, pairing a green tritium/fiber optic front sight with a black outline and a green tritium rear sight. The DI system is built around an industry-first, patent-pending interchangeable fiber design, letting owners replace the fiber in the field and choose among several fiber and ring retainer colors to build a personalized aiming solution. The fiber itself is chemical- and heat-resistant, finished with the same proprietary technique Trijicon uses on the ACOG, and it’s paired with a tritium lamp capped with a sapphire jewel so the sight stays visible from daylight brightness through complete darkness. Professional installation is recommended.
