Flat blade gives a crisp, target-style sight picture that eliminates the distracting Òdouble-notchÓ found on factory sights. .160" high blade (same as factory) features an angled and serrated rear face that reduces glare. Extends over the rear of the sight body for a cleaner look and gives a slight increase in sight radius. Available in two notch widths, .110" for target and PPC use, plus .125" for IPSC, IDPA and pin shooting. Deeper notch gives easier eye alignment.
