I've never owned a S&W nor do I care to, but it's not their responsibility to eat the cost of a gun destroyed by bad ammo, nor is their responsibility to deal with the ammo manufacturer.
This part might get deleted, but I find it childish to assume you're entitled to anything from S&W if it wasn't a defective gun, and that they should compensate you in any way because you "feel" that you shouldn't have to deal with it and they should just "make it go away" for you.
Every time we pick up a gun, we assume and accept responsibility for those actions. In the event of a malfunction we have the right to try and determine the cause and expect reparation from the RESPONSIBLE party. We do not have the right to ask any one else, company or otherwise, to make good on another's mistake.
