Rugged, fixed rear sight features a precision machined LPA dovetail for easy replacement of a fragile adjustable sight to make your gun more suitable for duty or carry. Extra-wide, .135" notch provides more light around the front blade to open up the sight picture for fast target acquisition. 50 lpi serrations on the rear face help eliminate glare. Allen head setscrew locks sight into slide dovetail for a rock-solid installation that won’t shoot loose. Regulates with most factory installed front sights. Machined from solid steel bar stock with radiused edges that help prevent holster snag. Minor fitting may be required. LPA fits Springfield Armory, Para-Ordnance and other pistols with the LPA dovetail. Will not fit Springfield TRP Operator.
U-Notch rear sight features a “U” rear cutout instead of the standard square notch.
