M&P 9 2.0 failure to extract causing double feed - solutions?

I think this is the right way to go, but if you haven't sent it yet, make at least one measurement.

If you have a micrometer or calipers, measure this distance:

Then when the new one comes in, you can compare to see if there is significant wear. This will be valuable information to all of us.

Shot the pistol for an additional 203 rounds yesterday at a major IDPA match. Cleaned & lubed the gun and cleaned magazines thorougly beforehand. Had one stage ruined by a Failure to eject at round #3,275, which was a different type of malfuntion, although still extractor related I suspect.

This time an empty case was stuck on the extractor. I dumped the mag and tap racked to clear it, but 5 racks was not enough to get it to eject. I eventually had to peel it off the extractor with my fingers through the ejection port. That cost me 15-20 seconds on the stage lol, but I expected a malf at some point in the match with this gun. Also, it was a 4th type of factory ammunition, Atlanta Arms Elite 147gr Match grade JHP's.

So now it has 3,347 rounds through it with 7 malfunctions between rounds 1985 and 3275.

The extractor claw dimension requested looks to be .3385" according to my calipers.

If you had to peel it off with your thumb, it sounds like an ejector problem, not an extractor problem.

I just happen to have a spare Extractor so, I measured it. Mine is measuring .346" which is at least .01" larger than yours. I do indeed believe your problem to be extractor related.

I would still send it to S&W and see if they replace it.

Have you done a lot of Type III malfunction clearance practice?

Interesting, was your extractor out of a 2.0 or an original? I suspect the 2.0 extractor is different, because for instance it doesn't seem like Apex advertises their aftermarket extractor as working on the 2.0. I guess I could take apart one of my old M&P's and compare but my 1.0's have generally been so reliable I've never needed to remove the extractor, even after 10k+ rounds through a few of them.

On Type III malfunction practice, no, because again my old M&P's were so reliable I never had to worry about it. Problem is they're all .40's and I'm trying to switch to 9mm. T've discovered that trying to use conversion barrels introduces reliability issues too (occasional double feeds on full size 40-9 barrels and in the compact 40-9, for some reason the magazine follower doesn't contact the notch on the slide stop properly all the time, resulting in magazines that won't drop free).

However I've come to expect the 2.0 to give me a type iii malfunction at any given time, so I'm always ready to drop a mag, rack the slide, and then take a look to make sure the chamber is clear before reloading. Not really acceptable to have it happening like clockwork once every 150 rounds. If I wanted a gun that wouldn't run more than 100 rounds without cleaning I'd be shooting 1911, and at this point I'm not even sure cleaning is helping.

I appreciate your information. I placed an order for a 2.0 for gun games and carry. I am very interested in the outcome.

My extractor is out of the original. Wait, it's also from a 45 which could be different. Ignore my measurement for now. I'm more interested in the comparison between what you have now and what comes back from S&W. That will be telling.

I asked because doing type III clearances is hard on the extractor. It could cause excessive wear on the claw.

Interesting comment. I'm going to assume you don't own a 1911? I'd put my 1911 up against any pistol for reliability. But that's a different discussion.

1911 comment was tongue and cheek but to me an M&P should be able to go a few thousand rounds w/o cleaning and not malfunction. I don't own an 1911/2011 but shoot my friends' and like them, they admit that sometime around 500 rounds w/o cleaning the slides start to slow down and they'll be getting malfucntions at 1k w/o cleaning/lubing though. That's probably because most 1911's made today have tighter tolerances than the original design to facilitate accuracy, but I'm just speculating.

I think any quality gun should be able to go a long time without cleaning.

I have one 1911 that I fired 749 rounds (one round was buggered from the factory or it would have been 750) in one sitting. No cleaning and no extra oil. I would have done more, but I just ran out of ammo.

My favorite gun finally had a malfunction at round 8,103. The extractor broke. Funny thing, the gun continued to operate, but I got a Type III malfunction. I cleared it and continued to shoot. Then, about 20 rounds later, I got another Type III. This caused me to look closer and I saw this:

That it continued to operate is amazing to me. I would have thought it would have a Type III on every shot.

Anyway, I completely agree that the M&P should go a long way without needing cleaning and without malfunction. You shoot a lot more than I do. I just don't have the time or money to shoot that much. I hope you get your issue fixed.

So after the cleaning it functioned OK for about 300 rounds. It had the same type of failure to extract at round 2,973 and 3,080 with Speer Lawman 147gr FMJ.

It was cleaned after round 2,598 including extractor removal and thorough cleaning.

That makes 6 times in a roughly 1,000 round stretch where it has failed to extract in the exact same way with 3 different brands of quality factory brass cased ammunition..

I just got a return label and will give S&W a chance to make it right.

Bump for an update once you get it back from S&W. I have (2) 2016 M&P9 FS 1.0 That both had (2) FTExtract in the first 125 rounds. Lost confidence in them & haven’t shot them since.

Wow, you keep that level of records of every round fired????

I keep an Excel spreadsheet that tracks every round that I fire through my Glock 17, 30 and my M&P 22 Compact.

It doesn't take any time to record the round count after I come home from the range and I think from a maintenance and ''selling" the gun perspective it is beneficial .

Following, as I had a similar failure recently with WWB 115gr. I suspect it was the ammo, but you never know. Love to hear from OP with an update.

For what it's worth, as a comparison, the extractor out of my 2.0 Compact at 2500+/- rounds is .340" give or take .001"

Sadly the problems I had with my 2.0 pretty much caused me to stop shooting firearms as a hobby as I was tired of playing amateur gunsmith to troubleshoot problems.

However, I did get the 2.0 that is the subject of this thread back from S&W and have fired 540 rounds through it without a malfunction. They replaced the extractor. I would want to put another 1500 rounds or so through it to really claim that it's fixed for good.

The luminescent paint on the front sight (trijicon hd) fell off after I got it back. Not S&W's fault, but I pretty much stopped shooting altogether because something always seems to be going wrong.

Thanks for the update. Don't stop shooting. It's too much fun!!!!
