I just never imagined anyone trying to skirt the FFL laws would create a record of sales by buying multiple handguns per day. But, it appears Mr. Crumpler was double stupid.
If you want to buy handguns in bulk, the multiple handgun reporting can be hard to avoid. You'd be limited to one handgun per transaction and can't purchase from the same place twice in a five day period. 529 handguns would take a long time to purchase.
