Regarding the frame problem; I too have had no problem with the functioning of the SD40. My only problem is that S&W told me to send it in and they would fix it but didn't fix it and didn't provide an explanation. This past weekend I came up with my own fix. I made a jig from scrap 1/4" ply wood and clamped it in such a manner that the dust cover would be pushed over into proper position. After applying a little heat to the dust cover with a heat gun, the frame is now perfectly straight. Very simple process. I don't see why S&W couldn't have done the same thing, considering they have a lot more experience with polymer than I have. Still disappointed in S&W but now the pistol is perfect.
