White line, V-notch rear sight and a white dot front post pull your eye to the front sight in high stress or low light conditions. Presents a very fast, highly visible sight picture to get you on target quickly. Low profile, no-snag design (even the top of the front sight body is rounded) is great for carry and combat competition guns. Matched front and rear sets offer direct replacement of factory sights. Big Dot provides improved speed when engaging targets at close range. Standard Dot gives better long range accuracy. Mfg: Xs Sight Systems
