Novak style cut, Standard .140" wide notch
Rear sights that fit slides machined for the Novak LoMount style .500 x 65 degree cut.
Three heights available - .325" (HD-004), .350" (HD-004.5) & .375" (HD-005) to fit all applications!
The HD-004 (.325") is the height of the original Novak LoMount sight, used primarily on Government Models and Commanders.
The HD-005 (.375") is the height of the "Tall" Novak LoMount used on the shorter 1911s, like the Officers ACP, Defender, Ultra Carry, etc. Also used on Springfield TRP pistols.
The HD-004.5" (.350") is the height of some new models like Springfield's EMP-4 and Elite Models. It's also a great problem solving tool for Gunsmiths working to get the perfect height sight set on a 1911 without having to go too short or too tall. My favorite for Commanders!
