I personally can vouch for S&W quality issues on there revolvers, bought a 629 several years ago, canted barrel, sent it back to S&W, got it back, still canted, sent it back the second time, finally got it corrected, my model 66, the reissue of it with the two piece barrel, ball/ detent crane lock up, after just 1 box of ammo it went out of time, didn’t send this back, my gunsmith who used to be a S&W warranty repair station fixed it and smoothed up the trigger for just $40.00, money well spent, so, yea, they have quality control issues, now my two current revolvers 625JM and my 610 seem fine so far. So what I have said did happen to me and wasn’t internet jibber jabber, it’s the truth.
