The distribution and sale of firearms requires transport across state lines. That is certainly interstate commerce. If the commerce clause is improper in this instance, then all the gun control laws based on the commerce clause are likewise illegitimate.

IMO, it is hard to find an issue that fits Interstate Commerce better than this. Forget that the product is firearms, it could just as well b automobiles or cheeseburgers.
