The Trijicon DI Night Sight Set for Glock 42, 43, 43X, and 48 brings dual-illumination technology to one of the most popular compact and subcompact pistol platforms. These steel 3-dot sights combine green tritium with green fiber optic elements, engineered to deliver a consistent aiming point in any light condition—from bright daylight to near-total darkness. Built for shooters who refuse to compromise on speed and accuracy regardless of lighting, the DI system stacks tritium's reliable glow against fiber optic brightness collection, creating what Trijicon calls an "ultra-bright" sight picture without batteries or electronics.
What sets the DI Night Sights apart is the field-replaceable fiber design. Unlike traditional night sights, you can swap the fiber rod yourself using the included torx key—no gunsmith needed. The set comes with two bonus green fiber rods, so you can experiment with different lighting conditions or have a backup on hand. The front sight pairs green tritium with the green fiber, while the rear sight features tritium only. All elements are finished with Trijicon's proprietary coating and capped with sapphire jewels for durability and light transmission.
The matte steel construction resists corrosion and blends seamlessly with Glock's factory slide finish. The black retainer ring provides contrast without glare. If you carry a compact Glock for work, personal protection, or sport shooting, these sights give you true all-light performance—the kind of reliability Trijicon has built its reputation on across decades of night-sight engineering.
