Just for kicks I will throw in my $0.02.
I just purchased my 2nd Sig 1911 22. Yep. I have two of them. I fell for the new style with the deep dark OD Green and the U.S. on the grips.
A little over $400 for a dedicated 1911 in 22 cal was worth it to me. No I don't shoot more than one at a time but I was able to shoot the 22 then the Sig SS1911 in 45 and then the 22 again without having to stop and waste time and money (range fees of $8 per half hour) to swap parts around.
I look at it the same way I do with having a 1911 in 9mm as well as a number in .45.
The Sig is the same size and darn near the same weight as the 45s so I don't feel like I am missing anything.
