M&P 9c Fail

[Racetruck17]

Hi Guys,

I recently purchased a M&P 9c to use as a carry gun once i have my permit, but the last two times at the range it has failed to extract the fired round completely resulting in a jam. The gun fired flawlessly for 250-300 rounds using pmc fmj's, but since switching to Winchester white box fmj's it has progressively had more failures. I had purchased four 100 count boxes of this ammo, and all boxes had ammo that jammed, i can't even complete firing one magazine without a problem. This gun was purchased brand new, and the best advise the seller will give me is to use the pmc ammo from now on. Before i get fed up and sell this gun, are there any common problems with these guns?
Thanks for any help!

Not to be insulting, but just to check... Have you thoroughly/properly cleaned and lubricated the gun since you bought it and between range sessions?

describe further the actual event. Is the fired case left sitting in the chamber? Is it pulled out but not thrown clear of the weapon? is it stove piping? that is, leaving the fired case caught upright in the ejection port caught between the breech and the slide? That can help diagnose the problem

[Racetruck17]

Sorry for the lack of information on my part... the gun has been broken down and thoroughly cleaned after every trip to the range, roughly every 50-75 rounds. No need to worry about offending me, I'll be the first to admit i am probably making some sort of newb mistake lol.
The actual set of events are the chambered round is discharged, extracted half the length of the case from the chamber, the extractor releases the shell and the slide comes to rest half open-not locked open.
Thanks!

If you go over to the M&P forum you will find that many, many owners are experiencing the same problems. http://mp-pistol.com/boards/index.php?showforum=14
It looks like it is a built-in feature! I note that the 9c is mentioned several times as being problematic. I had exactly the same problem with WWB and just about exactly the same number of rounds through my new Pro. The gun has been out of commission for several weeks now with another problem, but that problem will probably have to be addressed next.

I have a M&P 9c that has had close to 10,000 rounds through it without many troubles except for when my recoil spring wore out. I replaced it and it ran like a champ.

I'd suggest you send it into S&W to be fixed rather than messing with it.

But were you shooting any Winchester White Box? Most say they never have problem with that stuff, but if there is a problem with a handgun, White Box will bring it to the surface, or be the problem itself.

My question to Racetruck17 is, how does it work with your carry ammo?

I bought my MP9c a few months ago. Several hundred WWB through it with no malfunctions. Using my reloads now. No suggestions.

I had to send both of my 40's back to S&W for the mag drop prob when they first came out, and each time i told them when i sent it in that there was a problem to eject and they gave it a tune up including polishing the ramp etc for free and sent it back all postage paid. Also the turn around is rather quick.

[Racetruck17]

Thanks for all the input guys! I'll be sending it back to S&W for a tune up it sounds like. I haven't fired any carry ammo as of yet, wanted to get a little cozier with the gun before i started carrying and feeding it the expensive stuff! Once i get it back i'll try to run 1K rounds or so before i trust it again.

I think I shot close to a thousand WWB. I've reloaded that brass a number of times too if that means anything.

This is why this silly auto-loading pistol fad is not going to last.

You probably plan to do this, but do call Smith, and I suspect with a new gun they will send you a prepaid shipping label. Failing that the store where you bought it should be willing to take care of sending it back for you. You may have to pay postage, but at least you are not having to go out to UPS/Fed EX shipping depot and some FFL will use the US Mail, which is sometimes less expensive.

Sorry you are having the issue, I own several M&P, and they have been Glock like in their reliability. I should add I don't use WWB, but friends do in their M&Ps and have not had issues. Good luck, they are fine guns.

Even with the FTE, 9 times out of 10 it unloads more rounds then a revolver before the jam!!!
In all seriousness, i am very happy with the gun, and i do realize that this is still a mass production piece with many moving pieces; in my opinion it's a wonder that 1 out of 3 new guns don't have these problems. I'm not writing off the M&P, I was just saying i'd like to be sure the problem is fixed before claiming it is.
Thanks again!

You always get the same frame as the serial # is registered.
