From my understanding it is illegal, even on your own property. With the exception being inside your home.
Glad I don't have to deal with that junk anymore. Ms is a right to carry state, no permit required. If you can legally possess it, you can legally carry it concealed, even in a motor vehicle. We have a CCW permit that gives a person the right to carry in businesses that have no CCW signs, schools, places of worship, government buildings etc.
