My handgun use has been limited to 3 handguns over the last dozen years.... a 45 LC, a 1911, and a Colt Python in 357....

getting a CCW and was looking at the MP 40...use to a 45 ACP for knock down power.. and feel a 9mm is just too wimpy....

guys I know locally are trying to talk me out of that and going with an MP9 instead...saying a 40 kicks too much for extended shooting....

I am considering the 40 over the 45 ACP, just due to magazine capacity, 15 vs 10.... and over the 9mm, I like the heavier bullet weights used in the 40s...

appreciate some input of resident experts here...
