Now having said all that what do I carry for personal defense and practice with??

9mm- nope
45ACP-nope

I carry a 40 S&W semiauto with a high cap mag and a b/u mag as well.45's may have better "Smack" but same size guns have less cartridge capacity. I am concerned about multiple bad guys. Most serious thefts in my locale are with multiple perps. More rounds=more better!!
