Good morning Gray-
As of yesterday afternoon, I've put 400 rounds through it. Yesterday, the gents on my pistol team got to shoot it too. Everyone on my team are IDPA "Master" except me. :-( At the level they are, they certainly have their favorite pistols on which they rely. Side note: They all shoot with optics too and are instructors.
One team member shoots an M&P 2.0 with Apex trigger. The others shoot either Sig P320's (Legions, X frames etc.) or CZ's. Each of these gents really, really liked this pistol and they're pretty critical. Everyone liked the recoil impulse and pointability/balance. Note: The first day I shot it I had the "standard" grip panel on it. Yesterday, I put the larger sized (not largest) on it which everyone liked better than the standard one.
Other thoughts (my own and team members):
*. The barrel is extremely accurate. We were all stacking shots on top of each at 25 yards. Note- This is more accurate than the team members M&P 2.0's barrel. It is on par with my Sig in the picture above.
*. Shooting various brands of ammo, some of questionable quality, the gun remained accurate and there wasn't a hint of a malfunction.
*. Trigger- This needs some work. Now, I really do like it but it can (and will be) lighter and cleaner. I've worked a bunch on my Sig comp gun to lighten and smooth our the trigger but, it remains "smooshy"; it's a 3.5lbs on average. This is kind of what made me roll the dice with this M&P. Having cut my teeth on 1911's, I'm always looking for triggers that break with a "pop". The inherent nature of the M&P gets closer to that. There's less take-up, over travel and reset. It's just a bit gritty and heavy; just over 4lbs. As mentioned in another post, I've already ordered an Apex trigger for it. My team mate has one in his M&P and it's fantastic.
*. Recoil impulse- This is a light gun. I haven't read the specs but I've been told it isn't any heavier than the polymer version. This gave me a bit of concern about how quickly I'd be able to shoot it as a competition guy. Note: It's 9 oz. lighter than what I'm used to. In the end, it shot very quickly and "flat". Since they lightened the slide so much and the bore is lower than my Sig, they're both on par. Bore axis- yes, it's lower on the M&P. Just my opinion, but I think people make too much out of that on a 9mm when it comes to recoil. With a proper grip it doesn't really matter. I will say though, that at least for me, a lower bore axis aids in the "pointability" of the firearm. Once again, just my opinion.
*. How am I shooting the gun?- In slow fire (no timer) I shoot it very accurately. As mentioned, I was stacking shots at 25 yards. With a timer, my splits at 15 yards are between .17 and .20 seconds. Those are A-zone hits. That's pretty good for me. I'm happy with it since with my Sig, I'm between .20 and .24. I think I can just work the trigger quicker on the M&P. I'm not a strong guy- I'm 6'2" and 175lbs. with noodle arms. The lighter weight of the M&P compared to the Sig lets me "drive" more quickly on transitions. Out of the holster to my first shot- I'm still quicker with the Sig. Again at 15 yards, I can draw and put an A zone shot in at 1.7 seconds on average. With the M&P, I'm at 2.0. I'm sure I'll get there with it but I only have two days on it and it does hang in my holster at my hip a tad differently.
Sorry for the long review but I hope it's helpful to some folks.
