Firearms; modifying scope of lawful carry. Effective date.

SB 858 modifies Oklahoma's laws on firearm carry by updating where concealed or unconcealed firearms are prohibited. It adds specific requirements for "secured" event properties (like metal fences and metal detectors) and clarifies that carrying is lawful on public parking areas, adjacent properties, parks, and school parking lots (with firearms locked in vehicles when unattended). The bill also allows private schools to adopt policies permitting weapon carry by staff with liability protection, and permits school districts to designate licensed personnel (e.g., security guards or reserve officers) to carry on school grounds. These changes directly affect firearm owners, school districts, private school entities, and event venues across Oklahoma.
