I've had 1911s that have worked right out of the box (Kimber/Les Bauer) and I have had 1911s that I spent more time futzing with to get right than I ever care to remember (Colt, STI, RRA, Wilson, etc). In the end, I want a gun that I can pick up - from anywhere - and know I could, with a very high degree of probability, defend my life with it as my only gun. So I got rid of all my 1911s - I don't have time to dick with machinery and I don't feel confident enough in them (in them, not with them) to carry them.
Just my $0.02.
