I'm with Depicts......
I love them all, but as far as which I shoot the most (that's a qualifier, huh?), it would be my SA 1911s. I have two and they get equal time at the range.
They may fall out of favor though.....I just received my new CZ 75B in .40 SW and I believe after handling it (haven't had it to the range yet), the 1911s may become step children.....
