The 1911 in ACP is just about the best concealed carry weapon in terms of stopping power. A good one is accurate, reliable, and comfortable all day, although I don't like to shoot more than 30 rounds in a day. Note: This little toy also has stopping power, but overpenetration is a potential issue, and it can be awkward to carry in some situations:
I have one. It’d be a bit cumbersome in a hallway, plus ricochets are a bitch.

Haha, yes that one could be a problem for going through a bit too much.
At .50 cents a pop, it’s expensive to shoot .45, I can see why more than 30 a day would be troublesome.
