The 1911 U-Notch Rear Sight is made from heat-hardened 4140 steel for durability and has a manganese phosphate parkerized finish for wear resistance.
Designed with a U-shaped notch and 40 lpi serrations on the rear for a clear sight picture, it's compatible with a variety of front sights and suitable for one-hand cocking.
It fits the Novak-style dovetail, comes with a hidden setscrew for secure mounting, and is fully dehorned to prevent snagging during draw.
