I'm not a particularly good shot, but I sometimes amaze myself with the groupings I get shooting offhand with my Springfield Loaded 1911. I don't know if it's the tighter fit, the better finish, or the full length guide rod, but at combat ranges with rapid fire it makes the target very, very dead.
From a strictly accurate point of view, my Ruger 22/45 mkiii is boringly accurate. As others have said, the combination of the weight of the gun and the poof of the .22 makes it almost too easy.
I don't even like shooting paper with it. It's a lot more fun to make a can dance since I can shoot out the orange dot center mass of a stable target in pretty short order.
