Tennessee DOES have Reciprocity with Georgia, and the adverse is likewise as well.
However, Tennessee Handgun Permits are SLIGHTLY more difficult to abtain then there Georgia Weapons License Counterparts.
Even essence the Reciprocity seems Skewerd, BUT the Reciprocity has been in place for quite some time.
Open Carry is, similiar to Georgia, Legal. Furthermore, BOTH States have exceptions to allow Open Carry without any need for Licensure, although they are somewhat considerably different.
