Truglo FIBER-OPTIC PRO delivers a sight picture that is fast and accurate for competitive and recreational shooters. A patented light reflector focuses available light from all angles onto the fiber for a brighter glow, even in low light conditions Ultra-bright fiber-optic front sight for fast acquisition Patented light reflector design Blacked out rear sight for increased contrast Serrated sight faces reduce glare Includes spare fibers and reflector tape Fits standard holsters Most fiber-optic sights gather light from the top and somewhat from the sides. A patented light reflector in TRUGLO Fiber-Optic PRO sights redirects light onto the entire surface area of the fiber Traditionally, the best way to make a fiber-optic brighter has been to make it longer; however, this decreases the sight radius. The reflector design allows light exposure on 360Adeg of the fiber-making it brighter without needing to make the fiber longer. Due to gun manufacturers' machining tolerances, point-of-impact may differ slightly.
