Mass. allows that if you have your sidearm on you, it can be loaded because you're in control of it, but you have to carry it concealed. Whereas in Maine, you had to carry your gun exposed or get a special add-on permit for concealment.
The laws are nuts. They're different everywhere and that's the problem. If the laws were simplified and adopted by all 50 states, it would more helpful to both sides.
