Effective immediately, Governor Perry has issued a proclamation that allows persons with valid license to carry a pistol (concealed handgun licenses) from Alabama to carry in Texas. All Alabama license holders will be required to follow Texas law while carrying concealed in this state including age restrictions and type of weapon permitted. This proclamation will automatically trigger a reciprocal agreement. Texas concealed handgun license holders will be allowed to carry in Alabama and must follow Alabama law while in that state.
