Shorter version of what fred said. It is a little like algebra. There are more variables than just bullet weight.

Recoil? In a 9mm?

I kid.

Good answers, but remember that in the end it's what *you* perceive. Sometimes muzzle blast can change someone's perception on how much recoil is actually there.

Which is why I always wear ear protection and close my eyes when shooting a 9mm.
