I just shot this gun today and it seems fine so far. What I did notice is that there is a gap between the ejector shroud and the frame where they meet in front of the frame. I also noticed after one box of ammo the cylinder already has discoloration, not just the chamber mouth area but the fluting.S&W told me if it bothers me enough to send it to them. Comparing the new 25 to my older 17&19 you can visually see the difference. After all this I have to say this damn thing shot nice. I'll shoot it a few more times and probably send it to S&W. I know S&W is not the only manufacturer with these type of issues.
