M&P 9 Pro problem

[Scott55]

I was shooting at our outdoor range this afternoon and the M&P 9 Pro had a failure to feed about half way thru a 17 round mag.
The slide is not fully returned to battery and I believe the live round is not fully chambered. I cant budge the slide forward or backward and it is not quite far enough forward to release the take down lever. The trigger has also not reset, so I'm kinda stumped on how to remedy the situation. Right now it is back in the safe with a live round stuck in it.
Any ideas would be appreciated.

I have all kinds of ideas but I don't know your capabilities. My advice is take to a gunsmith, or a gun store with knowledgeable employees. It almost sounds like you have a squib or a partial case separation that is jamming the new round from chambering. If it's a squib (bullet stuck in the barrel) then you got lucky. I don't want to tell you what I would do because I don't want you to get hurt. I'm presuming that your firearm mechanical knowledge is limited because you're asking the questions. Not intended as an insult.

Ok, problem solved. I just needed to get it in on the bench and really apply some rear ward hand force. The slide came back and ejected the round.
So I'm all good. Just never had that happen where it was jammed so tight to not be able to hand rack it.

Time to look inside the bbl and at the cartridge, also see if you messed up the feed lips on the mag...

Was it Tula brassmaxx ammo? I had this ammo lock up my slide similar to yours on my pro.

My youngest daughter was shooting my 5" Pro the other day. We had purchased a box of remanufactured ammo. As she was shooting a round "jammed" the gun. From my 1911 days, I knew that I did not need to be gentle. I got the slide to open (tugging really hard on the slide) and we got the live round out of it. The top of the case had been squished on one side, thus causing a bulge. I am convinced and so is the gunsmith (who happens to work where I shoot) that the one round came that way from the box of remanufactured ammo. It was not pleasant. But the youngest knew something was wrong, tried to fix it herself and then wisely called me up to the shooting stall to fix the issue.

Another reason I make my own ammo. (and run every round through a case gauge before I use it). I even(especially) run factory ammo through the gauge in the rare event where I have to use factory ammo at a match.

It was Winchester White Box. First time I've really had any problem with it, but it is the cheapest stuff around here to buy.
I cleaned the gun last night and could find no damage to the feed ramp. I won't get another chance to shoot it for at least a week since I'm going out of town tomorrow.

Bkreutz,
We too reload. That time I had shot all the reloads that I had brought with me when she called and asked if she could join me at the range, thus the ammo purchase. All of the ammo we reload, gets checked for primer height, bullet height and every round gets dropped into a barrel to make sure every round falls in and out smoothly. The worst thing that has happened with our reloads is a piece of cracked brass got through. It was found when it was taken out to use. Dropping in the barrel helps insure that no Glock bulge cases got through. Though the Dillion 550 does do a wonderful job resizing the cases.
