What GC said. If you are serious about more energy on target,
get a 10mm Auto. Instead of necking a 40 S&W case down to
9mm, leave it a .40 cal/10mm, and stretch it out some.
I think you want a certain pistol, so get what you want, but
choose a chamber that won't break the bank, or have you
searching for ammo, when you want to shoot it. Given a
certain model comes in 9mmx19, or 40 S&W, I would likely
choose the 40 S&W for self defense, or the 9mm for
competition/fun shooting. I can't see any reason I would
choose a 357 Sig.
