Revolver folks, I still debate between owning a semi or a wheelgun. I am considering an S&W 686 as a possible buy, so my question is this: 158-grain +P LSWCHP or otherwise, would you trust your life to a .38 special? Also, I think I would like a 4" instead of a snub, as I gain a round. But in terms of accuracy and velocity, does 2 more inches of steel really matter? Am I better off with a snub?
