What about for non residents of Missouri?
Non-residents can open carry: "The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States" [Article. IV. Section. 2. U.S. Constitution]. What they cannot do is defend themselves or property under castle doctrine, since it is not their property. In Missouri, Oath Keepers from out of town have a duty to retreat if they can safely avoid the risk of harm or death.
