my wife has a Mark III I don't think its the hunter model though. Its a swet shooting little gun, with the heavy barrel and all. You should be able to do a number on the squirrels with a little preactice. Personally I use the Ruger Single Six. I can do better with it than I am though... I know a few guys on here use the Marck III, check the thread "handguns for squirrels" or somthing like that. I saw one guy has one with a holographic sight on his.
