For that limited of use, then the Cobra Derringer (assuming the .22lr is the same quality as the .38spcl) would be fine. I shoot mine for Cowboy Action Shooting side matches, it gets a good deal of practice, probably a hundred rounds a month (which is quite a bit since the side matches are typically only a few times a year and only two shots each). I also use mine for "swatting" downed upland game, #9 .38spcl shotshells work rather nicely for this. You don't really want a $200+ gun that you'll only shoot a few times a year, my Cobra has held up for two and a half years at 100rnds a month without a hiccup...and I bought it new for $80
