I just Got this M&P 40, it was traded for my old Maadi, haven't tested it yet, maybe next week when I have some time. The Bbl is 1/4" longer than my G23 and the grip is longer than the G23 and makes 2 more rnds than the G23 but if I insert the G22 15 rnd mag it's about the same length. It has the interchangeable back strap system and came with 2 15rnd mags NIB Seems like a great gun incorporating all the advances in striker fired guns over the yrs. This model have the safety and will fire without the mag inserted. Anyone have experience with this gun? What should I expect out of this one? What do you think of my new toy?
