How does 9mm feel compared to .40 or .22?

I have a M&P 40c with a 9mm barrel as well. I prefer the 40 over the 9mm. It's more of a push than a snap IMO. Might be the way the M&P is built. To me though it's the best way to go as you have 2 choices in the same firearm. It's like buying one gun and getting another one for just over $100. I shoot a lot and the only time the 9mm gets used is if we're shooting SMG's so I don't have to sort brass to find the 40's.

Me personally, I shoot the 45 and 9mm better than the 40, prefer the 45 mostly. If buying ammo off the shelf very hard to beat the 9mm.
