I'm a new guy here too. I've had a CCP for a long time, and sometimes I've got into town OC, usually with my 1911 in a Bianchi pancake. One time, I went to the barber, and the whole time I was there, nobody seemed to get excited.
I've gone into the P.O. (CC), without incident, but I wonder what would happen OC....with the "no weapons" notice on the door and all
