One last thing to throw in about SA. They have a lifetime warranty.
As youve observed there have been spotty experiences with Kimber, when its good its good and when its bad its real bad. My Dan Wesson CBOB broke part of the hammer off and I was within the warranty and was given a bit of a run around getting it replaced. This was 10+ years ago and before the acquisition by CZ, etc. but they finally relented and replaced it.
What Id say to you is that having a lifetime warranty on a gun like this is probably a wise move. I dont know what RIAs warranty is, but I know SA CS has pretty much always had positive reviews. Coming from a Glock world where of course youd get warranty support - this is a change in temperature.
