>>The Kimber is investment cast and the Colt will be milled out of a solid piece of steel. The Colt will hold value better in the long run. If you could find an older model forged Kimber you would be fine. Mac <<<<
The quote above is not accurate. Kimbers are forged frames, always have been. I have both older original Kimbers and the newer "Series II". Very similar other than the added "Schwartz" safety device and some MIM parts.
I also have a Colt Series 70 Gold Cup NM.
I think for shooting, Kimber. For resale (if you are a collector and worry about that) the Colt.
The Kimber always shot everything, the Colt, not so much. A spring change and some work made the Colt more reliable but it was made for a specific purpose, not just popping hollow points at paper.
The lesser quality 1911's often have cast frames, some good like Caspian frames, some not so good like the Phillipine made lines, RIA and such. Even STI has cast frames in some of their lesser models like Trojan and Spartan, but, like I said Kimber, Colt, Wilson, some STI all forged. The Desert Eagle, pictured above is a cast frame also. (Like Ruger shotguns, Ha ha, couldn't resist that one.)
