RE: .22 hunting handgun
I would reccomend for a semiauto-ruger mk 2 or mk3. HANDS DOWN!!!
Yes,the buckmarks shoot good,have a couple of disadvantages. First is they only have a wire for ejector. Second is you have to remove the whole top to field strip with an allan wrench no less.
As far as revolvers,look at S&W k22 and ruger single six hunter model.
