Not trolling in rich waters for a settlement. The businesses would all be stupid to settle, since they're all pretty well covered by the aforementioned Act, and this will probably get dropped quickly. The claimed basis for the case is that such an evil gun shouldn't even be available for sale to civilians. Even without the lawsuit protection act, they'd have a tough time winning a case with the primary claim being that a business was doing something they don't like, but that is perfectly legal.
