No longer true.As I understand it (I live in Missouri), if there is a city ordinance that forbids open carry then you are not even permitted to carry concealed without a CCW permit.
http://www.thetruthaboutguns.com/2017/03/daniel-zimmerman/truth-missouris-constitutional-carry-law/Putting it as simple as possible, the new law made it legal to carry concealed where it was already legal to carry openly. There are two problems with this.
1) There are provisions in Missouri’s law that allow cities to pass local ordinances banning the open carrying of firearms (Branson is one of those cities). The way around those ordinances was to get a CCW permit. The new constitutional carry law did not address those ordinances, which means if you do not have a CCW permit, you are not legally allowed to carry a firearm open or concealed in those cities.
Local municipalities have the authority to ban “permit-less” carry within their jurisdiction as well so you may need to check with local authorities so you don’t violate an ordinance without realizing it.
No longer true.
The oddity, said NRA lobbyist Whitney O’Daniel, of Carbondale, Ill., is that people will be able to carry concealed weapons in St. Louis and other places that limit open carry. A pistol in your pocket, yes, but not in an Old West holster on your hip.
