I've had a new M&P .40 since they came available. I love how it feels, shoots, looks, etc. I've had a couple of problems with it though: First one, it shipped missing a roll pin that goes through the frame near the rear on the "beavertail". Actually, it could have came loose and fell out during shooting; I didn't notice until after first range session. If it was missing all along, luckily enough the piece held together for the first shooting. No problem, after calling and telling them about it they shipped me one no charge. Next problem is the rear sight shot loose and fell off. No problem, just reinstalled using red lock tight. Next problem, or maybe not; hoping you all can help. The front of the slide has quite a bit of up/down play between it and the frame, probably around 1/8 inch. If you look at the piece it looks like the slide angles up from rear to front. Is this normal? Are yours the same?
