I have a 9mm, 40s&w, and a 45acp along with my 357sig. My gun club has steel plates at their pistol range and I am able to shoot out all my ammo I bring with every gun except the 357sig.
The plates can take as much ammo I send down range with every gun. When I shoot them with the 357sig the welds break on the backs of the plates after a few rounds. That tells me the 357sig is hitting the plates with a lot more force than any of the other calibers.
Thats a fact the 357sig hits harder!!!!!
