The Model 340s are not for everyone

A 12 ounce Scandium 357 Magnum J-frame is not going to be FUN to shoot

However it was not designed for FUN.

These were designed to give you maximum power in a minimum sized package, they were designed to save your butt when you end up in a bad situation. For that, they do their job well, Very well.
if you are in a situation where you can carry heavier or larger firearm, then that's great.
