RE: .22 pistol
Ruger Mark II. A family member has one and at 25 yards it was very accurate. I don't know if he got quite as good of groups as my Ruger 10/22 but at 25 yards they weren't far off. We both were shooting free handed btw. It's got quite a long barrel but is very accurate at least at 25 yards. Walther P22 is another popular one but I'm not sure how accurate it would be as it has a short barrel. May be accurate though I'm just not sure.
