I guess I don't undertand the intent of the question.
My Ruger LCP (misfed) (officially purchased NIB from a FFL) (a month later) was shipped to AZ via UPS store and returned to my doorstep from Ruger via UPS truck. Lawful owner back to lawful owner.
"Yet a FFL Dealer cannot ship a firearm to ones address" Had I purchased the LCP from a non FFL and been the owner prior to shipping to Ruger would of been no difference. Lawful owner back to lawful owner. Do we want this to be mandated to go through an FFL? Not me. Can this be exploited? Potentially, but it sounds like a "gun show" loophole.
