Best weapon for Concealed Carry advise

I carry what is comfortable for me, and that’s a walther ppk 380 hardly know it’s there. Is powerful, not really but unless a person is methed out of there mind someone is not going to walk into that. My wife has a 22 she is really comfortable with it and that is key. When I was just out of high school I bought a 45 acp for carrying, I can count on my hands the amount of times I carried it, just too uncomfortable.
