I purchased this gun 8 months ago when it blew apart in my hand after only 7.5 grains of HP-38. So the bottom loading round for .357. I sent my gun back because it was very obviously metal failure not over pressurized load. This is all Smith had to say. Smith & Wesson have informed me that they do produce all of their revolvers with "weak points" in them in case of over pressure the gun will come apart like mine did. But in my unfortunate case there was no over pressure it was simply do to metal failure and they refuse to stand by their product or help me in any way. I've tried calling but their representatives have been unhelpful and argumentative. I would never purchase another gun from them and would like to warn others about my horrible experience so other people don't have to go through what I did. It was a very expensive gun for me to only own 8 months with maybe 300 rounds through it.
