Welcome aboard! Your 357 is enough for dear as long as you are aware of your capabilities. If you are not comfortable with a 357 then buy another barrel. If you are like most of us you will end up with a bucket full of them any way. The 357 max is a lengthened version of the mag. It is within a couple hundred fps of the 35 rem if I'm not mistaken. As for the grips, I hate the stock wood grips. I have never found one that fit me. All my contenders sport Pachmeyer grips. KN
