M&P 9C more failures to extract!

[MJM]

after about 2500 rds my m&p9c began producing frequent "double feeds". Sent it to S&W and they replaced extractor, polished chamber and thought i was all set, not the case . still having FTE with WWB, Remington, Blazer Brass, Federal. any suggestions before i go out and buy a Gen 4 Glock 19? well, i will do this anyway, but i would like to hold onto my M&P and get it fully functional.

Strange given that it's a duty/ combat pistol But at the end of the day it's just another gun. Not all of them are perfect.

First-Send it back to S&W again. If you yell loud enough they will replace it with a new one.

Second-Get the Glock.

 

[Mass-diver]

Send it back again. Obviously, you are trying different mags, right?

 

[Supermoto]

is it double feeding or failing to extract, or failure to eject? Double feed is usually a mag lip dimension issue, failure to extract is a extractor failure to eject is an extractor or ejector issue

 

[MJM]

yeah, different mags/different ammo to no avail. i find it odd that it ran like a top until about 2500 rds. Shouldve taken a pix yesterday of the malfunction but here is the description. not a true double feed iguess. what i see is a spent casing about 1/4 extracted from the chamber, the following round not entirely stripped from the magazine(obviously) with its nose up against the spent round. i have not had any failures to eject ie stove pipe situations, but this is the 10th or so of this malfunction despite the work s & W has done on it.

 

[Supermoto]

The extractor is coming off the rim, either not enough tension or the extractor is bad. sending it back to SW is the cheapest way, sending it to a proper gunsmith would be the best way to fix the issue

 

[MJM]

thanks. SW already "replaced/tuned extractor" not sure what they will do this time around. ANy good SW smiths on here?

 

[Supermoto]

I would take it to Greg Derr in Marshfield MA.
I would rather pay to have it fixed correctly then screw around with S&W

 

[Youradolt]

Buy a Glock

Whats the frequency of the failures? You mention this is the 10th or so malfunction but out of how many rounds? Is it 1 out of 10, 1 out of 100, 1 out of 1000? If its happening very often I would agree with Supermoto. If its 1 out of 1000 it could be something else. When you did get the malfunction, was the extractor off the round and/or was it easy to hand cycle and eject the round?

 

[MJM]

may just take it to Gregg. in terms o frequency i'd say that atleast this past weekend i had 4 of these malfunctions/100 rds. The extractor was off the round. also it did take a fair amount of muscle to work through it and eject the round. does this help for diagnostics?thanks guys

 

[wolf223]

did you have someone else shoot it? just curious...

i have my GF shoot my G17 which is a TANK, and she had issues (limp wristing ect)... same type of symptoms you described...

if you haven't had someone else shoot it, i'd start there.. i disagree with paying a gun smith unless it's custom work. you paid for a product and it should run flawless out of the box... IMO

This is important IMO. I would take the barrel out and inspect it. It sounds like the case is getting stuck. 4 things come to mind - The build up of shooting 2500 rounds and lack of cleaning has caused it to get tight so the case is getting stuck. 2. The barrel wasn't reamed properly + some build up is causing same issue. 3 - You had a misfire, racked and fired again which has caused a bulge. I wouldn't think it would be that close to the chamber but who knows. 4 - The chamber is very tight and some of the ammo doesn't have the right crimp which is causing it to get stuck.

I originally thought limp wristing as Wolf said but I'm going to go with case getting stuck from what you've described. If you disassemble the gun and hold the barrel, try putting rounds in the chamber and see how freely they go in and out. You may find the issue there.

If only that were true with everything we buy new! I agree with the statement but I am still pleasantly surprised when a brand new gun functions perfectly out of the box. Then again, after 2500 rounds, the gun is no longer "brand new". Regardless, S&W should make it right, and if they screw it up again with the second attempt, send it off to Greg. If he gets it to run 100%, send the bill to S&W () with a nice letter stating how they should search for technicians who have 1/8th of the talent Greg does.

thanks for the input. i actually did take the barrel out and all rounds seemed to chamber easily and fall free without any trouble. i also cleaned the crap out of it after the first one of these malfunctions just to be safe, you couldve eaten off it. SW, supposedly polished the chamber and replaced/tuned the extractor but still the problem persists. i have not had anyone else shoot it because it happens randomly and i am not sure i'd get the info i was looking for. i too question whether it is an ammo issue but out of all my handguns i have never had any extraction issues.

I had this issue many time with my mp40c. Sent to them and had the same issues again. I ended up getting rid of it. Second Smith and Wesson semi-auto that I have had problems with. No more. Good luck.

Look into the Apex Tactical Failure Resistant Extractor. If I remember correctly, it's about $45.....

 

[btnh6668]

Interesting. Ive owned 3 M&P's and have never had any issues. I guess sometimes you just get the odd one that doesn't function.

I have a 40c and bought it new. I had one FTF within the first 30 rounds and now i have put nearly 1500 rounds through it with not one issue.

This is a long shot but replacing the recoil spring assembly might fix the FTE issue. If you had a marginal spring in there to begin with, it may already be fatigued by 2500 rounds and slide velocity may not be within the range that lets every event of the firing cycle happen with the correct timing.
