I'm with growr, check with S&W. I bought my 457 used, but it was in great condition and it has never burped on me. Given that most of us consider the 3Gs to be top end, I'd be curious as to what was happen; especially given it is happening on two of them.

I certainly sympathise with your problems. I have a fair share of 3Gs in my collection and I love them. And, I carry them regularly, as do other folks. So, please keep us in the loop on what you find.
