What role does .357 caliber play?

Exactly. That's why I take my 357 to the range every time. I get it out and shoot a few rounds to wake everyone else up. Heads pop out at the first shot!

Nice. I wonder why though. It has the same pressure as 40. Heck it even has practically the same case! I wonder what 10mm sounds/feels like in comparison
