Since we are talking about lawyers and not about squib loads, wasn't there a case somewhere about a guy using a 10mm for his CC load. The apposing attorney made that an issue.
Hell, I carry a 10mm on the farm all the time. Mostly because of hogs and that is a stainless gun. Hard cast LBT also.
I still might carry that gun when I go to the "big city". But I have some kind of hollow points in it.
