(a) Local option on the legality or prohibition of the sale of intoxicating liquors, wines or beers shall be preserved to each county. The status of a county with respect thereto shall be changed only by vote of the electors in a special election called upon the petition of twenty-five per cent of the electors of the county, and not sooner than two years after an earlier election on the same question. Where legal, the sale of intoxicating liquors, wines and beers shall be regulated by law.

(b) Each county shall have the authority to require a criminal history records check and a 3 to 5-day waiting period, excluding weekends and legal holidays, in connection with the sale of any firearm occurring within such county. For purposes of this subsection, the term “sale” means the transfer of money or other valuable consideration for any firearm when any part of the transaction is conducted on property to which the public has the right of access. Holders of a concealed weapons permit as prescribed by general law shall not be subject to the provisions of this subsection when purchasing a firearm.
