I just got a new M&P M2.0 10mm 4.6" a couple of days ago.
Got the model 13388 with the Thumb Safety.
Got to test fire both magazines full of 180 grain FMJ and it functioned flawlessly.
(That was all the range ammo I had til I just got more yesterday)
Looking forward to shooting it more.
I REALLY like it and am glad my nearly 3 month search to find one is over.
It looks like it has excellent chamber support too!
Sorry for the blurry picture.
