Actually this crap will eventually get settled in the courts most likely. While I think the gun manufacturers will ultimately lose as it doesn't prevent them from making guns, it'll cost the state millions to defend the law against organizations like the NRA.
Frankly I'm surprised these companies didn't pack up shop and move ages ago. Guess the cost is what prevented it up to this point.
