I only have the (1) magazine that came with the gun. Maybe if I get with another M&P owner, I could eliminate that problem by using theirs. I did read on another forum about a guy adjusting his extractor (I don't think I would do this personally-warranty issue?). He said his problem went away, then came back after a few hundred rounds.
I'm going to go ahead and contact S&W tomorrow, just to hear what they have to say about the situation.
