Oh...and let's not have them clarify the question of which holding an AR pistol buffer tube to your shoulder is legal or not (there's your face palm). I mean the intent of a 'pistol' should be fired from the hands and not supported from other parts of the body, but hey I have never seen a letter saying I "can't" do it?
Actually:
It is CLEARLY spelled out that a Pistol is to be used with a SINGLE hand.... as such, given this latest "determination" it would seem that using both hands to hold your pistol would make ANY HANDGUNS AOW's....
Check it out.
