ORS 166.433 Findings regarding transfers of firearms

The people of this state find that:

(1)

The laws of Oregon regulating the sale of firearms contain a loophole that allows people other than gun dealers to sell firearms at gun shows without first conducting criminal background checks; and

(2)

It is necessary for the safety of the people of Oregon that any person who transfers a firearm at a gun show be required to request a criminal background check before completing the transfer of the firearm.
