Trijicon 600545 HD Night Sights Green Tritium Yellow Outline Front - Glock 20/21 Large Frame

The Trijicon 600545 HD Night Sights are a self-illuminating tritium sight set purpose-built for large-frame Glock pistols, including the Glock 20, 21, 21SF, 29, 30, 31, 32, 36, 37, and 41. Configured as a classic 3-dot aiming system, the set delivers fast, intuitive target acquisition in low-light and no-light conditions without batteries, switches, or electronics to forget.

The front sight uses a green tritium lamp ringed in a yellow photoluminescent outline for high visibility against dark backgrounds, while the rear sight pairs green tritium with a black outline to create strong contrast that draws the eye to the front blade. The tall front blade profile provides a clearer sight picture over the slide.

Manufactured from hardened steel with a corrosion-resistant black finish, the HD (Heavy Duty) series sights are engineered for the rigors of everyday carry, duty use, and home defense. Tritium illumination provides years of maintenance-free service, and the sights install as direct drop-in replacements for factory Glock dovetail sights. Sold as a complete front and rear sight set in new condition, ready to install on your large-frame Glock.
