After working in a Gunsmith Shop for a few years, I can tell you the pistols that we saw come through the door the most were the Colt 1911A1. We loved them! They were great money makers for the Gunsmithing Industry.
The ones that we saw the fewest of were the Springfield's and the Kimber's. If I had to choose a 1911, I would probably have to go with the Kimber. They are really well made, and shoot very well directly from the factory box.
However, understand that I personally am not a 1911 Pattern Style Pistol lover. I don't like the way they feel or handle. For the .45 ACP Cartridge I prefer the H&K USP .45 ACP. I love the .45 ACP Cartridge, just don't like the 1911 Pattern.
Also, I don't like a pistol that requires special tools to field strip and clean it. This is a throw-back to its original designer. It hasn't been changed for more modern designs for ease of maintenance. The bottom line is the fact that there are just better ways of doing the same job.
As I said though, these are just some of my opinions and not to be taken as anything more. But again, from experience working in the shop, the Kimbers are by far one of the best choices for the 1911 Pattern gun.
Good Luck and Happy Shooting!
