Hmm... Took another look at the P22 today. Personally, I think if you're looking for a "serious" .22 (ie. your first) I'd look for a Buckmark or a Ruger Mk.II depending on which suits you. But since I do have a Buckmark (and my girlfriend has the Ruger-angle covered, not that I like its grip angle all that much anyway...), the P22 could make a nice addition to my humble collection...
The SA trigger was pretty good, thinks I. Not superb, but good enough. The DA trigger OTOH sucked, much. Heavy, long, spongy. Nothing like my P99 (well, ok, that one has a long DA trigger pull too, but otherwise much better than the P22!). I was wondering, does it get better with time, or can your standard gunsmith fix it for you, easily (ie. low cost...)?
Other than that, from just handling it I have no complaints. Haven't had the chance to fire it though. The grip is really small, but then again I have small hands too, so it's fine with me. And suppressing it (the longer-barreled model that is) should be real easy. All in all seems that if I had the money, a P22 would make a fine candidate for a "fun gun".
