very nice pistol, I keep debating on getting the MP 9mm.
My wife has the M&P 9. We went to the range once and had a number of failures to eject, feed and fire.
The 1 failure to fire could have been the round...the firing pin certainly left it's mark.
The other failures occurred with my wife firing the gun...could have been limp wristing, I don't really know. I fired a couple of magazines through it myself and never had a problem, but she did most of the firing with that gun on that particular day. I'm going to take it to the range again in couple of weeks and run at least 100 rounds through it to see how it performs for me.
I got the gun for her to use as a home defense weapon. Since she is having trouble with it, I'm strongly considering the Taurus Judge or Public Defender for that purpose...we'll see.
