Bill No. 628 amends Section 1277 of the Oklahoma Statutes 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. It also clarifies that certain properties, such as municipal buildings and courthouses, can be designated as firearm-prohibited locations. Additionally, the bill updates statutory language and provides definitions and restrictions related to the carrying of firearms in various settings, including schools and public events.

Key changes include the removal of the term "federal" from the list of governmental authorities and the introduction of provisions that allow municipalities to permit concealed carry by authorized personnel. The bill also specifies that firearms may not be present in designated firearm-prohibited locations, such as police departments and courthouses. Furthermore, it establishes that municipalities can create policies for the open carry of firearms in public buildings. The act is set to take effect on November 1, 2025.
