I just got a brand-new M&P 340. Haven't even gotten to the range with it yet (rain).
I've only played with it a few minutes now, and see where the cylinder has put about a 1/4" vertical scratch, down to metal, on the black finish on the side of the frame. When opening the cylinder, the back edge/corner of the cylinder rides against that little ridge that sticks out on the frame...that's where the scratch is.
Anybody seen this happen before? What should I do, see my dealer on Monday, or will I have to talk to S&W about it? Or is that just the way they all do?
If my description doesn't make sense, I'll take some pics tomorrow.
