Trijicon DI Night Sights build on decades of tritium and fiber-optic engineering with an industry-first interchangeable fiber design, letting you swap fiber and ring retainer colors to configure a personalized aiming setup and even replace the fiber in the field.

Dual illumination pairs a chemical- and heat-resistant fiber (finished with the same proprietary technique as the Trijicon ACOG) with a tritium lamp capped in a sapphire jewel, amplifying collected light for an ultra-bright aiming point from daylight to complete darkness. This set fits Glock 20, 21, 29, 30, 36, 40, and 41, including the S and SF variants.
