http://en.wikipedia.org/wiki/Protection_of_Lawful_Commerce_in_Arms_Actthis is what protects gun manufacturers
and do you know why you are crying about your 7th amendment rights being "violated", and that you so desperately want to sue the gun manufacturers - hint is has to do with you being the minority position (as usual)
BECAUSE YOU CANT GET THE VOTES IN CONGRESS TO PASS THE LEGISLATION - so you want to use the courts to push your MINORITY agenda. did it ever occur to you why cant you get the votes????? because the MAJORITY of (US)DEMOCRATS would prefer criminal control over gun control and the MAJORITY of (US)DEMOCRATS realize that the bans haven't worked in other countries they wont work here and we will be handing the congress over to the republicans (again). so go ahead keep crying and whining and citing false facts, keep yelling at the top of your lungs because you do not speak for the majority of US/we/Democrats.
take a look at this thread - many different people have tried to point out your obvious errors, and you wont listen well that is your right but look closely at the posts you are the majority of posts on your side. (feeling lonely ahhh poor j - not to worry, there are a few other fringers out there - I'm sure)
