basfu, I believe you are wrong.
Here is the proper statute
790.33
Field of regulation of firearms and ammunition preempted.
—
(1)
PREEMPTION.—Except as expressly provided by general law, the Legislature hereby declares that it is occupying the whole field of regulation of firearms and ammunition, including the purchase, sale, transfer, taxation, manufacture, ownership, possession, and transportation thereof, to the exclusion of all existing and future county, city, town, or municipal ordinances or regulations relating thereto. Any such existing ordinances are hereby declared null and void. This subsection shall not affect zoning ordinances which encompass firearms businesses along with other businesses. Zoning ordinances which are designed for the purpose of restricting or prohibiting the sale, purchase, transfer, or manufacture of firearms or ammunition as a method of regulating firearms or ammunition are in conflict with this subsection and are prohibited.
(2)
LIMITED EXCEPTION; COUNTY WAITING-PERIOD ORDINANCES.—
(a)
Any county may have the option to adopt a waiting-period ordinance requiring a waiting period of up to, but not to exceed, 3 working days between the purchase and delivery of a handgun. For purposes of this subsection, “purchase” means payment of deposit, payment in full, or notification of intent to purchase. Adoption of a waiting-period ordinance, by any county, shall require a majority vote of the county commission on votes on waiting-period ordinances. This exception is limited solely to individual counties and is limited to the provisions and restrictions contained in this subsection.
