Trijicon HD XR™ Night Sights - Glock Large Frames GL604-C-600840

The Trijicon HD XR Night Sights GL604-C-600840 takes the proven HD night sight platform and refines it for shooters who need more precise target identification and engagement at increased distances - built with the demands of law enforcement in mind and delivering next-level capability beyond what standard HD sights provide for large-frame Glock owners.

The GL604-C-600840 fits Glock models 20, 21, 29, 30, 36, 40, and 41, including S and SF variants - please note this sight set excludes MOS models and is not compatible with the Glock MOS platform. The Glock Night Sights GL604-C-600840 purpose-built fit ensures correct dovetail installation and proper HD XR sight alignment on compatible large-frame platforms. Green tritium lamps are warranted for 12 years from the date of manufacture. Professional installation is recommended.

The defining improvement of the Trijicon HD XR over standard HD sights is the thinner front sight post - delivering a larger field of view around the front sight, enhancing target visibility, accelerating target identification, and allowing more precise shot placement at distances where a wider front post would obscure the aiming point. For law enforcement officers and serious defensive shooters who need to place precise shots at distances beyond typical close-range engagements, the HD XR thinner post is a meaningful capability improvement over the standard HD configuration.

The Yellow Night Sights GL604-C-600840 yellow photoluminescent ring around the front tritium lamp maintains warm, high-contrast front-sight visibility that naturally draws the eye under stress. The Tritium Sights green illumination provides self-luminous performance in complete darkness without batteries.
