Hmm, thats not good, better give S&W a call and see if you can get that looked at.
KEN N said:Is any one else having trouble with ammo? I think my M&P might be over rotating 180 gr bullets. Some leave odd shaped holes in the targets, as if the copper coating is comming off before impact. Its happened with a couple diffrent Mfg. but never happened with 165 gr. or 135 gr.
