The Trijicon Fiber Optic Sight Set for Glock Standard MOS Models provides an ultra-bright, battery-free open iron sight system engineered to accelerate target acquisition for duty, competition, and tactical shooters. Drawing directly upon advanced light-gathering chemistry from Trijicon's battle-proven ACOG series, this setup uses a highly reflective fiber core to maximize daytime front post illumination. The sight arrangement combines a thin 0.110-inch front post with a non-illuminated, glare-resistant square-notch rear blade designed to cleanly isolate your focus on the front dot and target. Entirely CNC-machined from robust solid steel and treated with a resilient phosphate finish, it seamlessly withstands harsh slide cycle g-forces and aggressive holster friction. Additionally, the rear sight is contoured with a steep, hard-angled front ledge explicitly designed to enable situational, emergency one-handed slide cocking off a belt or rigid barrier.
