Is there anywhere here on the forum or anywhere else as far as that goes that would tell you what frame size you have if you have model XXX? I was also wanting to know if there was a link/list that would tell you what calibers match up to frame sizes/model numbers? For example if I had a model 29 I could look and see that it is frame size "XXX" or if I wanted to know what models were available chambered in the .44 mag it would tell me the different model numbers/frame sizes.Thanks in advance,Travis
