Looks like smith and wesson doesn't honor it's lifetime warranty. Was at the range last month shooting my 9mm shield at the plate rack, on the 5th round the firearm exploded in my hands, extractor broke poking a hole in my cheek. It had fire out of battery, call s&w, sent in back. Got a letter saying that an over pressurized round did the damage, no fault of the firearm. I was shooting blazer factory ammo. Ya it was over pressurized, when it was detonied before getting into the chamber. Needless to say I'm done with any new s&w guns coming out on the market, I think their Quality Control need a good look at some of their new designs. The barrel and slide are ok, they survived.
