There are 60 degree and 65 degree bevel cuts on the 1911-A1 and several different heights. Why not email Kimber and get it from the horse's mouth? It looks like Kimber uses a different set-up as I see Colt 1911 and the Kimber's have two different model numbers in the Brownell's catalog for Novak, Ashley, Wilson, MMC and Mec-Gar.
Looks like the dimentions are a bit different:[list]
[*]Colt Government (mil-spec) = 0.170 x 0.125"[/*]
[*]Kimber = 0.145 x 0.125"[/*][/list]
So they're a bit shorter than Colt mil-spec.
Bomar makes two different read sight dovetails and they both measure 60 degrees x 0.359 x 0.100"
There are about 20 different sights available in the Brownell's catalog for the Kimber without having to alter the pistol for the Bomar slot. Milling a slot into a 1911-A1 is a $30 to $40 job plus refinishing if needed.
