You're almost right. What this means is that firearms laws are not in the domain of municipal governments. Only the state can make laws in the area of firearms. And since the ultimate state law, the constitution of the Commonwealth of Kentucky only allows restrictions on concealed carry, neither the state nor any local government unit has the authority to make laws that contradict it, short of amending the constitution.
"No City, County, Urban-County Government may occupy any part of the field of regulations of the transfer, ownership, possession, carrying, or transportation of firearms, ammunition or components of firearms or combinations thereof.
Effective: July 13, 1984
History: Created 1984 Ky. Acts ch. 42, sec 1, effective July 13, 1984"
Am I to understand that the local cities and counties cannot infringe on the right to open carry? Did I interprate that correctly?
