High quality sight systems offer exceptional brightness in a low profile configuration that won’t hang up in your holster or slow you down. CNC machined, steel construction provides superior durability for combat or competition. Dovetailed rear with set screw (except Sure-Sight) and screw-on front sight makes replacement of Glock®factory sights fast and simple. All sights, except Sure-Sight, match factory sight height. Fiber optic rods produce a brilliant shine in bright and low light conditions without battery power. Contrasting green rear and red front ensures fast sight recognition and alignment. Rear sight features two individual fibers for maximum surface area to collect ambient light. Rods are recessed and fully protected in the sight channels to survive the toughest blows and remain hidden from your target.
