South Dakota governor Kristi Noem recently signed into law a bill that allows lawful residents to carry concealed weapons without obtaining a permit from the state. The shift makes South Dakota the 14th state to enact "constitutional carry".
It looks like that number may soon be raised to 15, as the Oklahoma House signed their own carry bill on Valentines Day. Indications are that the bill will pass the Senate. On September 4, 2018, governor candidate Kevin Stitt said he would sign such a bill if it reached his desk. From news9.com:
“I would sign it. I am a constitutional conservative. I support the first amendment, the second amendment and I think the best defense for a bad guy with a gun, is a good guy with a gun,” said Stitt.
Stitt was elected in November with over 54% of the vote. It remains to be seen if he will keep his word.
