I agree the E series Smith and Wesson is a nice gun. So is the Ruger SR1911 if you can find one. The E series has a better feel to it. You might also consider the Sig series of 1911 pistols. I have one that has never had a malfunction.
If you are thinking polymer, take a good look at a Springfield XDM4.5 or a Glock 21 for a full size or G30 for a small .45.
The G30 is a great gun and it comes with 10 rounds of attitude adjustment.
