Missouri Gov. Jay Nixon has signed legislation allowing state employees to keep guns in their vehicles, while they are on property owned or leased by the state.
The bill also allows fire chiefs with concealed-gun permits and special approval to carry weapons on the job. And it bars governments from running gun-buyback programs unless those guns are later offered for sale or trade to licensed firearm dealers.
Nixon vetoed Friday a bill that would make some federal gun control laws void in Missouri.
