Mississippi is an open carry state and the state constitution appears
to guarantee this right. However, the legislature has confused the
issue by the wording of their concealed carry law. OpenCarry.Org is
working with Mississippi officials in an effort to clarify this. In
addition to this issue, under their weak preemption, localities may
regulate the carrying of firearms. For this reason, we have labeled
Mississippi as 'indeterminate' for the time being. The good news is
that open or concealed carry in any motor vehicle is perfectly legal.
