Fixed rear sight is precision machined from heat-hardened 4140 steel bar stock, so it withstands the wear and tear of daily carry, yet delivers a clear, precise sight picture. Perfect for concealed carry, duty, or combat pistols where a rugged, reliable rear sight is mission critical. Fully “dehorned,” with rounded and chamfered edges to prevent snagging on holster, clothing, or other gear that could impede draw. Easy-to-acquire .125" high U-shaped notch aligns quickly with a wide variety of factory-height front sights, including fiber optic, tritium dot, and gold beads. Rear face of the plain black blade has 40 lpi serrations for a glare-free sight picture under almost any light conditions; front of the blade has ledge contour to aid in one-hand cocking. A hard, manganese phosphate parkerized finish that matches many tactical pistol finishes adds strength and surface wear resistance. A hidden setscrew helps anchor the sight in the slide dovetail for extra-secure mounting and resistance to shifting under recoil. Cut to fit the popular Novak Lo-Mount-type dovetail.
