I'm always wary of guns that have been customized by previous owners. There are way to many kitchen table gunsmiths out there who's dremels have turned very nice guns into expensive paperweights.
If you want a Colt, take a look at a new XSE Commander. If not, then the Sig would be the way to go. I personally don't care for the odd slide profile or the external extractor, but they do build some nice guns.
I think you need to re-read the OP, because he's considering a Sig 1911, not a P Series. Even then, both Sig's 1911's and almost all of the P Series guns sold here today are made in the U.S.

They are the Audi of guns: finely crafted in Germany, pricey, but you get what you pay for. And unlike 1911s you don't get a $3000 target pistol you are afraid to drop or a cheep GI model that nees $1000s in "upgrades" A Sig is a shooter right out of the box. There is a reason the SEALs carry Sigs...just sayin.
