I have a very new Smith and Wesson M&P9mm full size. It is less than 2 months old with less than 500 rounds through it. Comes with everything from the manufacturer including the hard case, three different back straps, 2-17 round magazines, all the paperwork, and the chain lock. Never had any problems shooting, not a single mis-fire or fail to eject. I will also include a Fobus retention holster. I'm looking to trade for the M&P9mm compact in similar condition to mine. The 9 has no magazine safety or no thumb safety.
