A rebarrel cures about anything that cain't be cured by less invasive procedures.
So, approach the Kimber from the perspective that you want one; you want that light action and damn nice stock and trigger. It'll likely shoot fine. If not, dab bed... crown... at this point you've almost certainly got a shooter.
And if THAT fails, $400-$600 puts a very fine barrel on there. And that's fun too.
Kimbers are worthy build platforms...
