As long as we are allowed to own domestic firearms, I don't see that the Heller ruling overturns any import ban.
The anti-gunners are already splitting hairs on this decision. Mayor Fenty of DC just said that all guns will continue to require registration, and that all "automatic and semiautomatic" handguns will continue to be illegal. Thus, if he lets you own a registered revolver, he has complied with the Heller decision.
Technically, a revolver IS a semiautomatic.
So Fenty wants to allow single-round guns? Sort of like a single-shot Deringer?
Fenty is an idiot.
