Being simply a "sport shooter", I have engaged in competitive rifkle, shotgun and handgun shooting who has no particular legal background outside of a couple of basic business law courses taken many many years ago I'm less than certain, howevaer mighyt it be that D.C.'s newly discovered legislative largess, allowing the law abiding to maybse register handguns, might that requirement still be violative of tjhe individual's Second Amendment Rights, especially as they so ignorantly describe what sounds like it might be a 1911 type pistol to be a "machine gun".
Seems to me that those clowns really need to be dragged over the judicial coals, this time cited for contempt of court, with suitable, spelled significant penalties imposed on those responsible for this ongoing foolishness..
