A good 1911 would be much more appropriate, and that’s not up for debate heh.
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:
