Requires universal background checks for all sales or transfers of firearms

HB 1545 requires background checks for all private firearm transfers between individuals who are not licensed dealers (such as private sales or gifts). It mandates that non-dealer sellers arrange for a licensed dealer or law enforcement to conduct the check before transferring a firearm. Key exceptions include transfers between immediate family members, antique firearms, temporary transfers at shooting ranges, and transfers due to death or inheritance. Violations would be punishable as a class B misdemeanor. The bill applies to all firearm transfers not covered by these exceptions, directly affecting private sellers and buyers outside of licensed retail transactions.
