+1 for Sig Sauer 1911. Best bang for the buck out of the box IMO. I have a few 1911s including Sig Scorpion, STI Trojan, and Remington R1E... All are great but you get a bit more gun from Sig. All Sigs are stainless frames and slides with Nitron coating. Nitron is a great finish. The Cerakote on the Scorpion is even better. But, go for what your heart wants - all brands you mentioned are great quality but go fondle some before you commit.
