I for one will never by a new Smith & Wesson revolver again! I got burnt to many times.
I have a 65-5 3" bought from Gil Hebard's in the 1980's. How fortunate I was, and how good that gun has turned out to be.
I've also bought a number of S&W revolvers in recent years -- Models 60, 640, 642, 442, 432. All have been excellent, with very good fit and finish. And I bought most of them sight unseen, from Bud's Guns, so didn't get to check them for cosmetic or more serious flaws (As noted by NJM15, under Bud's policies, you can refuse to accept a gun if there is a flaw, but only BEFORE IT IS TRANSFERRED by the FFL to you. Once it is transferred, Bud's tells you that your recourse to a problem is to contact the manufacturer). Fortunately, no flaws were found in any of them that I can think of right now (I can think of another major brand revolver I bought that had a problem eerily like the OP's, but in that case two charge holes that would not release the brass, not discovered until I shot it). All my S&Ws have been accurate and reliable, and aesthetically almost up to the standard set by that 65-5 (which has aftermarket wooden grips now and sits in the dresser drawer as the primary defensive weapon protecting hearth and home, with one speedloader, a Streamlight, and a set of ear plugs next to it).
So, while I understand your comment (which apparently springs from some bad experiences) I would advise anyone interested in buying a S&W revolver today that it is a good bet you'll get a fine revolver when you buy a S&W... and S&W will take care of you if you have a problem, which unfortunately can happen.
