MG, for you I would suggest starting out with the 617 or one that's not on your list, the model 63. Light recoil and cheap to shoot makes for a great way to start in live fire. Once you feel that you're ready for a 38 spl. look into an older tapered barrel model 15 or 67, that light weight barrel makes for a superbly balanced 4 inch 38 spl..
