After all the remarks and the troll statements about my experience. I am going to try to post pictures and show the reply I got from Smith & Wesson. I sent the ammo that was involved, but did not receive it back because I was told they were not ammo manufacturers so they could not ship it back. They did not test the ammo because "we do not test ammo", but I was required to send it back. I had an M&P 40 that exploded with Winchester white box 40 cal ammo. I sent the gun and the ammo to Smith & Wesson. I am posting hopefully the letter I received. Anyway, to those of you who said there were no pictures, and pretty much called me every name in the book. Here is your proof. I am screwed, I have nothing to show for this but a $779.95 pistol that did not function. Don't tell me I paid too much. I have already talked to the dealer I bought the pistol from and they were afraid to pursue the problem because of their relationship with Smith & Wesson.
