Re: USA made 1911 for around 1k
Springfield loaded stainless, or any springer with a NM s/n prefix is made in USA. I don't think those frames come from Brazil, but I could be wrong. No import markings, so unlikely the blanks could be from Brazil, but when they cut the frame, they do it in the good ol USA. The NM springers are fit VERY tight bushing to barrel, probably tackdrivers from what I've seen.
Other than that, I'd probably lean STI at $1000, most bang for your buck. For a nice new Kimber, I'd rather spend more, seen bad quality control at their $800-1000 range.
