Was recently in the market for a high capacity 9mm for home defense. Found a GREAT deal on an M&P full size, 17 round at Academy. After getting it home and stripping for cleaning, I noticed I didn't get the standard S&W packaging...no lock, no spent test round, the serial number is laser etched on the slide and the barrel along with US POL and a 16 digit code. The barrel was really dirty. I've put a couple hundred rounds through it with no problems. I'm just curious.
