Um, fwiw, I just did the SA-Loaded versus Kimber Classic Custom comparision over the last few weeks, prior to deciding which one to buy. Surfing the various forums for praises and complaints, found plenty on both sides for both brands.
Most common negatives mentioned on the forums on the SA-Loaded seem to be the 2-piece guide rod unscrewing on some, rear sight set screw unscrewing, rear sight dovetail cut too loose and the rear sight drifting around, sharp edges, and fatter frontstrap. Most of the looseness problems are said to be fixable with Lok-tite or teflon tape on the guide rod threads, but that was still a concerned to me...
When I handled one at my local shop, the sharp edges everywhere were a major negative to me. The fat frame was okay, although I'd prefer the contoured Kimber frame.
Most negs on Kimber are the occasional one with feeding problems, too tight chambers, etc.
Anyway, I finally broke the 'tie' by asking long time 'hardcore' 1911 shooters at my local club. While some recommended Kimbers, none recommended SA's, at least not without sending it out for an upgrade package (e.g. Bilby). Not scientific, I know, but what the heck...
I opted to get a Kimber Heritage Custom Classic that I lucked out finding on sale and so far, after 400+ rounds, it's been running flawlessly. So I'm a happy camper...
Fyi, I bought a 1991-A1 Commander that's turned out to be quite the lemon. Jamma-matic from day one. Sensitive to brands of mags. Chronic last round jams, even with factory 7 rd. mags. Has turned into quite a project gun, trying to debug this little sucker in my spare time. Tried all the 'usual suspects' according to the 'how to' 1911 books. Replacing the factory slide lock lever turned out to reduce much of the problems. (hmmm. Not in the book...) I had previously adjusted and readjusted the extractor, polished the breechface, etc. (Too cheap/poor to send it out for professional help...) <g>
Otoh, I bought a Colt Combat Target a couple of years back and it has been flawless from day one... Go figure... Put together on a good day, I guess....
Fwiw, most of my Colts tends to have a very loose slide/frame fit, whereas the SA's and Kimber's I've seen have a much tighter fit...
These days, about the only choices in shops in my area are SA's or Kimber's. Colt 1911's are getting rarer and rarer.
