I shot a fair amount of competition but my experience is with a fairly small range of pistols. I've never shot a free pistol, for instance, and one of those is probably the most accurate out there. In my experience, the S&W Model 41 and High Standard Supermatic were the most accurate. The Ruger Mark I Target too (I havern't shot the later models). For centerfire, the National Match 45s turned out by the US Army for competition were the most accurate, although not quite as accurate as a good 22.
