Trijicon HD XR Night Sight Set w/ Green Tritium Rear & Yellow/Green Tritium Front for Glock 20, 21, 29, 30, and 41 (incl. S & SF) GL645-C-601169

The Trijicon HD XR Night Sight Set for Glock Large Frames delivers an advanced, long-range tactical design engineered specifically for Glock models chambered in 10mm Auto and .45 ACP, including the G20, G21, G29, G30, and G41 (including all S and SF variations). Forged from robust, heavy-duty phosphated steel, this system utilizes an ultra-thin 0.122-inch wide front post that expands your side-to-side sight window to allow for highly precise, extended-distance target tracking. Self-luminous green tritium gas lamps are housed within shock-absorbent aluminum cylinders and capped with sapphire windows to provide a crystal-clear, battery-free point of aim in zero-light scenarios. The front post features a brilliant, glow-in-the-dark photoluminescent yellow outline to lock in eye focus immediately during rapid daylight transitions. For clean sight alignment, the rear face features a wide "U" notch with a glare-reducing serrated surface, while its steeply hooked forward edge assists operators with emergency, single-handed slide cycling.
