I'm not sure if the main srping had been replaced. My gunsmith doesn't think so, but he was was suspicious that the side plate had been removed at some point, which would indicate potential fiddling with the internals.. I bought the gun on Gunbroker from the Kittery Trading Post; they claim the gun was NIB. IF S&W can resolve the problem and I can get the gun working properly I MAY ask my gunsmith to "polish" the internals for smoother operation. Actually, the double action on the gun is already very smooth so that may not be necessary or desirable. However, before I do any modifications I need to ensure that the gun is firing properly.
Bingo
Theres so much more that goes into it aside from a spring swap.
Surprised that no one mentioned the rebound spring. It can have the same effect on light strikes.
Bet my bottom dollar that OP's revolver has been mucked with.
