I have a Full size M&P9 1st Gen with a complete M&P40 factory upper to come with it. Shoot 9mm or swap out the complete upper and shoot 40. Both calibers shared the same frame so it is completely interchangeable. I put an Mcarbo trigger spring kit in it with an apex trigger shoe, fantastic trigger! Comes with 2 17 round 9mm mags, 2 15 round 40 mags, Blackhawk OWB holster and the box, factory trigger, paperwork and everything else it came with new. Excellent condition!! Buyer pays transfer fee. Located in Chesterfield va. I am looking for $600 in cash or trade for a Glock 19 gen 5 or 6, preferably COA or MOS. Thanks!
