The serious shooters on the Bullseye list swear by the S&W 41. They also swear by some of the MUCH more expensive Hammerli and other exotic guns, but we're talking BIG DOLLARS for these other guns. The S&W 41 seems to be the best bang for the buck for serious shooting. I've seen them in the $550 range, new, and you might be able to do better -- or think "used."
The Bullseye shooters also like the Ruger MKII target Competition, but grumble about its mediocre (by serious bullseye shooting standards) trigger. Many upgrade with a Voltquartsen trigger and other supplements. A good gunsmith can get the same results.
The new Sig Trailside has opened to mixed reviews, with some very vocal detractors. Especially among SIG enthusiasts. I've been surprised. (Similar to the Hammerlis mentioned earlier, I think.)
The BuckMark has many adherents, but Gun Tests magazine recently panned it -- observing that taking the grips off can turn routine cleaning into a major production, as key pieces and springs are held in by the grips. Sproing!
I have a Target Competition, and it shoots far better than I can -- and I got it for well under $400. Ruger's no questions asked lifetime warranty is hard to beat.
(Incidentally, I've never met anyone owned a Beretta .22. I've heard from a few who've shot them, and they were not generally overwhelmed. May be a good gun, but there are too few around to know for sure.)
