What's the deal on 40 cal, keep hearing weird references to the round.
It's a high pressure round and has more recoil impulse and muzzle flip than 9mm and .45 ACP.
I am indifferent to it. I think .40 and 9mm could both stop someone dead as long as you can connect. Accuracy is more important than the never-ending 9mm vs 40 vs 45 speech.
If you get the M&P, I would strongly suggest the .40 for the reason I mention earlier in this thread. But CZ also makes some sweet guns. Hell, just buy them all.
