Hi, I am looking for a used S&W revolver that shoots .38. I know the .357 will shoot them, but I am not sure what models over the years they have made that I can be on the look out for. Does anyone have a source that I can type in the caliber I am looking for and it would tell me which S&W models shoot the .38 special? I am looking for a longer barrel like a 6" if that makes a difference. I also don't care if it shoots the +P as I will probably never shoot that or .357 rounds in them. Thanks for the help...........Bandman
