Trijicon HD Night Sights for Glock 21 – Yellow Outline

The Trijicon HD Night Sights deliver a high-visibility three-dot sight picture for defensive and duty use on the Glock 21. A tritium front lamp provides 24-hour illumination, while the yellow photoluminescent outline absorbs ambient light for instant target acquisition in varied lighting. The wide U-notch rear sight allows rapid sight alignment under stress.

These sights are purpose-built for the Glock 21 (.45 ACP) and install using a standard sight pusher tool. The front sight features a taller profile to clear suppressor-height optics when co-witnessing. Steel construction with a matte black finish resists corrosion and wear from holster draw cycles.
