I bought my M&P 9C about 2 years ago and I've fired THOUSANDS of trouble free rounds through it. It is a superb pistol. Yours may have a tight chamber or a bad extractor. That stuff happens. This weekend I was on the range with a guy who had a brand new Armalite 9mm. Sweet pistol BUT it shot about 12 inches low at 23 yards. He needs to send it back to Armalite. I wouldn't say they are junk or condemn the company because of it.
