Bill No. 628 amends Section 1277 of the Oklahoma Statutes regarding unlawful carry of firearms in certain places. The bill modifies the list of locations where carrying firearms is prohibited, allowing municipalities to authorize employees or public officials to carry concealed handguns under specific conditions. It removes the prohibition against carrying firearms in buildings owned or leased by federal authorities and allows for concealed carry in municipal buildings, provided they are not designated as firearm-prohibited locations. Additionally, the bill updates the definition of "minimum-security" provisions and clarifies the conditions under which firearms may be carried in various public spaces, including schools and parks.

The bill also introduces new provisions that permit municipalities to establish policies for the open carry of firearms in public buildings and outlines the training requirements for municipal employees authorized to carry firearms. It specifies that firearms cannot be present in designated firearm-prohibited locations, such as police departments and courthouses. The effective date for this act is set for November 1, 2025. Overall, the bill aims to provide greater flexibility for firearm carry regulations while maintaining certain restrictions in sensitive areas.
