My SIG P220 is the most accurate of all my autoloaders (pity I don't own a P210 anymore, though). It'll do sub-2" groups off the bags all day with abhorrent gunshow-bullet-in-a-bag reloads. It is simply unerringly accurate and reliable. The most accurate gun I own is a girl-next-door S&W 686 6" which is apparently telepathic; it puts the bullets exactly where I want them, every time, all the time.
