More BG2.0 testing to report...
I am up around 300 rounds on FMJ range ammo without any issues.
Just ran 50 rounds of Hornity FTX Critical Defense without any issues using that, will likely use that for carry.
I earlier had FTF issues with Fiocchi hollow point, as have others.
Lehigh Defense XD (Phillips style tip) and similar bullets have also been reported by others as problematic for this gun.
The sights as set by S&W measured very close to being centered (within 0.002"), but the gun shot low and left.
I adjusted the sights by about [EDIT/CORRECTION] 0.024" and it now shoots straight but a bit low.
Had an instructor test it out at the range after adjustment and it was right on for him so the low part is evidently on me.
EDIT:
Also, the 10 round mags have loosened up some from the numerous reloads that I can now get a fully loaded mag in the gun with the slide closed, although it can take a pretty good wack to do it.
