The slide is supposed to stop on that part of the frame not on the spring binding, but it is not supposed to be able to damage the frame like what I think I may or may not see in that blurry a$$ picture :wink: I would definitely give S&W a call they will want to take a look at it.
as a side I know they shot 40K through a M&P 40 with no spring changes what so ever and did not get any damage to the frame at all.
