Having shot 357 snubbies, I'd say there is no practical reason to get a .357 and absolutely no good reason to have one. They are the most brutally painful handguns to shoot, the recoil is straight back and fast into the web of your hand.

I do own a .357 snubbie but only load 38 special level loads in it. I'd much rather have a lighter built for 38 special in a snubbie.
