In mass they call it a "LTC" or "Licence to Carry". I have a class A large capacity concealed licence and I carry all day, everyday. Ususally I carry my Berretta .25 with a spare magazine for a total of 14 rounds. Sometimes I carry the Smith & Wesson .357 Magnum 5 shot revolver with 5 spare rounds in my pocket. Gotta pack heat.
