To top it off, Saiga was never mentioned by name- just an "shotgun importation ban"... except in the Prince Law blog
could have been the Taurus Raging Judge 28ga (if made in Brazil, would be imported, and by any measurement is legally a DD)
The ATF reportedly visited Taurus to inform them... this could all have started from a flippant remark by an agent, frustrated because Taurus apparently doesn't have lawyers smart enough to understand the DD definition...
