Call Kimber, they will give you the information you need. That's what I did. In my case, I wanted to make cuts for the Kimber Meprolite sights in a slide that had no dovetail cuts. Kimber gave me all the specs.
I have also installed a Dawson Fiber optic front sight in a Kimber Gold Match, and TruGlo TFO fixed sigths in a Kimber Custom II. In both cases I ordered the sights for Kimbers, and they fit just fine.
As I recall, the cuts for the fixed sight and target sight guns are different.
