I'd get a excellent condition, real-deal, unmodified Colt 1911 Series 70. I picked up another one about nine months ago for $500 - a good deal. Like-new ones, are easy to come by at $700. Totally stock, utterly reliable, classic and collectible.
Restricted to your list, I'd go with the S&W. Unlike the other items except the Kimber on the list,
1) It is a US made, forged frame
2) Has no buggery internal lock or other trigger-based safety system.
The S&W and Kimber meet those criteria. The S&W has had rave reviews from shooters I've met or read about, and comes with a LIFETIME WARRANTY. That is a heck of a selling point. It does have a Firing pin safety, but it works off the grip safety, not like the trigger-based one in the Colt. Kimber's had some teething problems and poor service reported, though I think it's ironed out now. However, no high-end Kimber has come close to equalling the accuracy of a well-built Gunsmith gun on Caspian components for the same price in head-to-head test. Given all that, I nod towards the S&W.
