Best weapon for Concealed Carry advise

I’ll add a little something to this, in California (not sure about other states) you can NOT modify any concealed carry firearm listed on your CCW. That is why I buy good handguns. I have a few that have been through custom shops (kimber and S&W) and are glorious to shoot. But they cannot be carried. I do not want to have to rely on a less than superior handgun at the most important time.

What's it like sending tax dollars to your masters every time you buy something, earn something, or wake up breathing? Do you enjoy paying to give away your rights?

I'm not sure with all the rounds available these days that .380 is considered weak. I mean I have a Ruger air rifle that'll put one through a human skull.

Details, man. This site has rules, and I'm sure somewhere in there is some requirement about telling us what make and model airgun will do such a thing so we know what to look for....

Link to a preferred seller would be appreciated too!
