The Trijicon Fiber Optic Sight Set for Glock Standard Frames offers a premium, battery-free open iron sight configuration designed to maximize speed and accuracy for tactical, competition, and duty shooters. Drawing upon decades of battle-proven illumination engineering from the iconic ACOG series, this tactical setup leverages advanced passive light-gathering physics to project an ultra-brilliant daylight focal point. The design couples a thin 0.110-inch front post with a completely blacked-out square-notch rear blade designed to absorb distracting glare and isolate your visual focus cleanly on the threat. Machined from solid steel and protected by a robust matte phosphate coat, the entire assembly seamlessly handles aggressive holster wear, heavy training schedules, and intense slide cycle recoil. Furthermore, the rear sight is aggressively contoured with a steep, hard-angled front ledge explicitly engineered to facilitate urgent, emergency one-handed slide cocking manipulations against a belt or rigid barrier.
