Not much you can do with a light weight short barrel LCR in .357. It was never intended to be a range gun, practice with .38's and carry with .357's. Then find something like a SP 101 or GP 100 or S&W 686 for target shooting.
Don't question my right to own a gun and I won't question your stupidity not to.
