My thanks to Pete at WRSA for bringing my attention to this from Oleg Volk.
In for a penny, in for a pound
When Germans came into Poland, Poles made no more sporting shotguns. They made Sten clones. When Russians went into Chechniya, Chechens made no sporting shotguns, either. They made various submachine guns. Should US anti-gun creatures succeed in driving regular rifles and shotguns out of legal circulation, they will see more submachine guns as well. Sound suppressors would reduce the risk of discovery by authorities as well as the muzzle blast, so having a silenced gun would be safer for the user. Seems to me that the American anti-gun activists don't understand just how simple open-bolt weapons really are.
One of the commenters at Oleg's site has thoughtfully posted this link to produce the homemade SMG illustrated above.
Making barrels with a CNC machine.
In a country where machine shops (and even CNC machines)are in every little town and hamlet, "banning" anything made of metal is foolish. And that includes thirty round magazines, Peggy Noonan.
