Sorry, but deliver of guns to felons should be prosecuted.
People forget that FELONS are not required to register their firearms. SCOTUS says so.

I resoectfully disagree
And no legal gun owner will disagree with you on that. But first you gotta ketch'em, and then the prosecutor has to do his (or her) job....which is where things mostly break down. This is one of those that usually gets "plea-bargained" away.
