Just got my gun back today! That was just over a week turn-around, so very fast.
S&W replaced pretty much every component of the cylinder locking mechanism, including the cylinder.
Much much better now and I'm pleased. Finally functions as it should.
S&W did not address the finish defect the frame but now that I am on record with having registered this complaint, I feel alright about going ahead and shooting the gun.
Only complaint left is a minor one--the new cylinder like the old one has the flutes slightly off center from the chambers. Not a big deal but it does look a little weird--(if cared to, I think I could have the flutes widened slightly to make them line up)
Shouldn't of had to go through this mess in the first place, but I'm satisfied with S&Ws response.
