Bill No. 628 amends existing Oklahoma law regarding the 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 circumstances. Notably, it removes the federal government from the list of entities whose properties are included in the prohibition and introduces a provision that allows municipalities to designate certain buildings 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 municipal properties.

The legislation also establishes that municipalities can permit the open carry of firearms in public buildings, subject to their policies. It specifies that individuals with valid handgun licenses who have completed additional training may carry concealed handguns while acting in the course of their employment. Furthermore, the bill outlines the responsibilities of municipal authorities in designating firearm-prohibited locations and emphasizes that this law does not create a duty for municipal employees to carry firearms as part of their job functions. The act is set to take effect on November 1, 2025.
