The gun under discussion is mine. I bought it on 12/16/2011, took it out to the range for a basic function check and rough sight-in. I used .38 Spl loads.
Then I brought it home and did an action job on 12/21. I was checking the timing when I noticed 7 flutes on the cylinder.
I emailed S&W Customer Service on 12/22. No response on the 23rd. I noted they were closed until 1/2/2012.
My dealings with S&W customer service have been excellent. They're very aware that this gun is the subject of threads on over a dozen firearms forums. They want to make me happy.
I sent the gun in using S&W's label by FedEx 2-day and they got it on 1/6 at just after 9AM. The label seems to indicate the gun went to the Performance Center. Since I requested an unfluted cylinder and PC handles those, I'm optimistic.
I kept the original cylinder.
The gun was signed off at the factory on 12/2/2011. That was a Friday and I suspect it was the last gun the inspector checked that week.
I'll be shooting in a steel match tomorrow and it'll be fun showing the cylinder around!
