My father always tells me, 'Life is tough and then you die'. I hope this works out to where you are okay with the experience. It seems to me there is a lot of opinion intertwined in this thread, but very little factual evidence established. Personally I do not see any proof that S&W, or Federal as the responsible party, as no one can prove that it was Federal factory ammunition, some other manufacturer's factory ammunition, or reloaded ammunition.
No matter what the strong opinions may be, I do not see the OP having convinced a 'Jury' of those that support gun ownership, so I doubt a jury of antigun advocates would see it his way either. I do not see this going to a trial, so I suspect the best the OP can expect is the very generous offer by S&W.
When the number of people in institutions reaches 51%, we change sides.
