Follow-up:
The first week of March, I finally sent the revolver back to Smith&Wesson. I got the return shipment one month later. Inside, the note that came back indicated that they had replaced the entire frame and destroyed the old one.
Upon inspection, I suspect that they replaced the barrel as well. The original revolver had sharp edged on all the etched characters on the barrel and on the frame. The characters were also a golden color. The new revolver has much smoother characters that are all white.
I am anxious to get to the range and fire it to test functioning. It appears that the cylinder shake issues are much less than on the example I sent in, and it is a much tighter fit at the rear of the cylinder when loading. Additionally, the firing pin appears to produce a fraction more. I'll have to keep my fingers crossed until I get a chance to test it.
Thanks all for your advice regarding warranty work.
