Remember that a gun chambered for .357 Magnum is only giving you more options. There are many many choices of ammo that you can fire in that gun.
BB makes ammo specifically to address flash and recoil.
As a handloader I have a wide range of powders and weights to choose from. I can match the energy of a 9mm, .40 or .45, or I can go beyond them all.
Where you set the dial is up to you.
In short, you can't go wrong with that gun.
