*** up with my M&P 9mm

shindaiwa6 · #1 08-01-2009, 03:25 PM

my m&p is being a pain in the ***. my rounds drop freely in my dillion case guage, the rounds feed into the gun, gun goes bang, then i have a failure to extract ( fired round is stuck in the breech). do i have a tight *** chamber? even if it's tight why doesn't the extractor do it's job?

You very likely have the same problem I had with a brand new gun. I sent to Smith and they "modified" the barrel and replaced the extractor.

Don't think you are the only one with this issue.

Sure sounds like 625 knows where of he speaks on it!
Could you both elaborate a bit more on it? 625 now and shindaiwa6 when he gets it back, please?
Thanks!

Spotteddog-

Don't have a lot to add except details of the symtoms. My brand new M&P 9 had a classic failure to extract right from the start. (As opposed to a failure to eject, which I experienced on two other M&P9's)

The gun would fire, but the spent casing would stay in the chamber. The result was that the cycle would be interrupted by the the nose of the next round being forced into the case still in the chamber.

After dropping the mag (or pulling it out) and locking the slide back, the spent casing could be easily removed. If the muzzle was pointed straight up, the casing would frequently just fall out.

Not rocket science, the extractor was not pulling the casing out of the chamber.

Smith repaired the gun and it worked fine when I got it back. Since that particular gun was going to be for primary carry and home protection, I elected to not trust it and I traded it off.

Smith's repair invoice was typically uninformative. It appeared as though there was some machining done to slightly lower the feed ramp, and the feed ramp was polished within an inch of its life. Obviously, the extractor was replaced also.

I have purchased four M&P series guns, and three of them had warranty return issues, all including failure to feed or failure to extract. The two that I have kept have been dead reliable for more than 3500 rounds between them. Their purpose in life is USPSA or IDPA competion, and I would not use anything else. I would also not buy another M&P.

Please forgive the ramblings.

My two M&P9 pistols were/are fully reliable. My first one, a standard pistol, shot high (

! ) and was replaced with a 9L, for that reason. The 9L has been a very good gun, in all aspects. Now, I wouldn't mind having a 9c, too...

The gun mentioned obviously has an extractor problem, if it does that with good quality factory ammunition. Tension may need to be set - or replaced.

S&W will fix it, good CS!

the only difference with mine is i needed to use a screw driver to get the spent shell out.

looks like i'll be calling smith on monday

Should have got a Sigma.
Seriously, the more guns I get, the more I respect that line of guns.
I was looking at my 990L which cost twice as much, and that
The Walther frame is not nearly as nice compared to the sigma.
The Frame lock is rough and off center and looks overly complicated, the Sigma is a smooth action and perfectly finished.

Sigma is simple, reliable, well made, no issues at all really.
All the bugs have been worked out and there is a lot to be said for that.
I wouldn't trade mine for a M&P.

Spotteddog · #9 08-02-2009, 02:30 PM

So what your saying is, that the chamber has dimensional issues? Or is it a case "finish" quality issues inside the chamber? Or possibly both?
Thanks for taking the time with this, I'm trying to learn all I can about the gun!

d625 · #10 08-02-2009, 03:16 PM

Sounds like the chamber could be undersized, especially if it sticks casings with different brands of factory ammo. If that's the case (no pun intended), the extractor just might not be able to do its part in the process.

Most of my experience with Smith is that they will fix it in a reasonable period of time and pay shipping both ways

Right now, you have an expensive hammer. Get it going to S&W

And at the other end of the spectrum have 3 M&P's that are used frequently in USPSA/IDPA as well as in classes that run flawlessly from the first round. The .40 Full Size has over 12,000 rounds downrange with ZERO malfunctions of ANY kind and just keeps getting better.
I wholeheartedly agree that S&W's Customer Service has been fantastic for me on a few 3rd gen. guns I sent to them. they were a pair of 4006 police trade in guns that were quite tired. S&W went through everything at NO CHARGE to me at all!
Second only to Dillon's NO BS warranty...S&W for me has been ALMOST no BS!

Are you using reloads or factory ammo?

jpwhel · #13 08-04-2009, 08:59 AM

The first time I took my M&P9c out to the range, I had a shot casing that stuck in the chamber and I could not get the extractor to remove the casing. Finally forced it out of the chamber. The casing did not look bulged and did not look defective. I then ran another 100 rounds through the gun flawlesssly. In my case I just figured it was a problem with the one casing since I could not recreate the failure to extract.

shindaiwa6 · #14 08-04-2009, 09:33 AM

using both factory and reloads. my reloads pass my dillion case guage. if i would take the rounds that pass the case guage, some of the rounds would fail the chamber in the gun. the rounds are either tight or will not drop in all the way

Spotteddog · #15 08-04-2009, 05:44 PM

While it certainly shouldn't be your responsibility to do so, it'd be interesting to slug that chamber to see what kind of numbers it runs out at?

WR Moore · #16 08-05-2009, 07:36 AM

Uh, you are taper crimping the rounds right? You need a very slight crimp to remove any trace of belling of the case for bullet seating and this could be the issue, especially if you're using lead bullets. Do factory rounds drop in freely? If this isn't an issue keep reading.

Call S&W customer service. If ammo dimensions are OK, it kinda sounds as if the chamber wasn't finish reamed to full depth. This type of thing isn't supposed to happen with CNC machining, but possibly the finish reamer was off a wee bit. Please remember that the weapon was function fired at the factory so, there weren't any immediately visible problems.

FWIW, I purchased a .22 rifle many years ago that was never finish reamed. This type of problem isn't unknown with mass produced products. Probably a minor issue with tooling setup.

got my pistol back from smith. note says they replaced the extractor and did a barrel modification.

will get to the range sometime in the year 2015
