I'm frankly a bit stumped with this right now, so since I have no idea where to start with this...here goes;
Please see attached picture montage for TL/DR and reference.
Recently got an M&P 2.0 9MM Compact 4" since Aimsurplus had a price that was just to good to pass up.
Bring it home, look it over, disassemble and check, etc, I see no bent things, no obvious machining marks, rifling looks clean in barrel, etc.
Give a very light lube with EWL, off to the range...
First few rounds, shooting way left. I figure, ok, new gun, different trigger, different size grip, probably just me. Relax, try again, paying more attention to trigger and sight alignment. Now shooting left AND low, at a whopping 10 yards. Odd, but I'm sure it HAS to be me, so load some more ammo, keep going- no improvement- POINTING center mass, but shooting left/low with occasional flyer back to center.
Ok, must be backstrap is to small for my hand; swap from #2 to #3 (#4 is just a bit to fat, #1 way to thin).
More pew; essentially same results, perhaps a bit lower even.WTF.
This continues for 100 rounds; I tried EVERYTHING; paying close attention to sight alignment, different backstraps, every possible finger position on trigger.
At this point, I'm sure I'm just failboating- I don't claim to be the best pistol shooter ever, and I'm a bit out of practice, so I bust out a couple different pistols to check against- a G17 (factory stock accept for gripforce adapter and Triji sight that I zeroed MYSELF) and M&P 1.0 Compact (also factory stock except for DCAEK and it has the Large backstrap). So two other pistols both significantly different in size, grip, sights and trigger press from the M&P 2.0...
Shoot a few rounds; within the limits of my ability, everything is MAGICALLY fine (SEE PICS #1 and 2)
So now sure that I CAN indeed still center-mass my groups, I go back to the M&P 2.0- exact same results- left, low and everywhere.
PER THE ATTACHED PICTURES- (see #3 and 4 for example). The shots are consistently left, with me POINTING the sights center mass, and applying decent fundamentals, with the occasional FLYER back to center.... It is so weird.
THESE ARE NOT the only groups I shot that day- the others were even MORE random, these just show the left/low consistency the best. Also I may have thrown out a couple of the other targets in a fit of pique...
It was like, 80% consistently left or low/left, AND THEN, out of nowhere, I'd get an "almost center mass" group (similar to PIC #5) and think "AHA! it IS me" and then the very next group was right back to left-left-left, DESPITE me doing the EXACT same thing that SEEMED to get me a "good" group.
So I have no idea what the hell is going on at this point.
I can still center-group consistently with other pistols, all of which vary significantly from the 2.0, which means to me, none of that accessory stuff matters that much.
So I think, ok, duh, sights are off, I'll fix that easily. Measure sights with caliper- sights are fine, about as centered as can be. Rear sight set screw is tight, space on either side of front sight is 6.44mm and 6.33mm , so a 0.11mm difference. Given this pistol is off by almost 2" at 10 yards, I'm pretty sure correcting this via sight adjustment is going to be a FAR bigger adjustment than 0.11mm at ten yards, right?
I mean, do the math with the pictures below- at 15-20-etc yards, the groups would either be completely off the paper or shotgun sized...
I have literally NEVER had a pistol be off with the factory sights, especially by this much, and that includes the plethora of beater rentals I've shot over the years.
COULD I HAVE GOTTEN A BLEM GUN? The magazines that came with it had a red stripe markered down the center of the follower (SEE PIC)- I have never gotten any other M&P magazine that has ANY mark anywhere on the magazine...???
Honestly the price was a little to good to be true, BUT...I trust Aim and the page did not say anything about it being anything other than factory new. I have not heard of any major complaints about accuracy in the 2.0 line either...
So today I went back out and printed some groups for reference with the G17 and M&P 1.0, and then shot a final group with the M&P 2.0 just to make myself feel good.
At ten yards, with the #3 backstrap that feels the best for my hand, and doing my best to apply good fundamentals, I got one of those "meh" "almost centered" groups I was talking about earlier, compared to the other two (last picture in montage). Considering the 100 rounds of low- left-and everywhere the other day, I am almost sure this was a fluke group, and were I to continue the results would be the same as before, BUT I posted it anyway, because even though I managed to reasonably center everything, the group is STILL easily twice the size of groups with the 1.0 Compact and G17.
I really have no idea what to do with this thing at this point, whether to give it another 100 rounds and see if it improves at all, or call S&W...
What so you folks think?
