M&P FTF issue

[elkslayer069]

I have a new m&p (500-600 rounds) having failure to feed issue everything I've found so far points toward the ejector. Some rounds go in slick as could be but others jam both fmj and hp same and different manufacturers. Just wonder if anyone else has had this same issue. Help would be greatly appreciated.

P.S is there a good pistol smith in sw washington?

Thanks Caleb

is it clean and are you shooting cheap ammo they can be a little picky on what they eat.

[elkslayer069]

Its clean and this is happening when trying to chamber a round right off the get go. The mags are new and clean and it happens with a full mag or with  one round in it. It almost like the rims on some of the cases are to thick to slip easily into the extractor

[MadHatter]

Does it do it with every mag? Also, does it shoot fine, or is it just feeding the initial round?  I would look at the feed lips and the follower on the mag being off and not lifting the round up high enough in the front to hit the feed ramp.

If that's not the case you might want to try a new recoil spring.  It might just not have enough "umph" to strip the round when loading from empty, or even when firing.

If it is pretty new call S&W and send it to them... They will make it right and wont cost you anymore than shipping it to them.  It's kind of a waste to spend money on something they will fix for free... That is unless you need it faster then they can fix it, but even then a lot of gunsmiths, at least ones that are any good are usually a week or two out, if not longer... I always hesitate to take anything to a gunsmith that doesn't have work on their plate... There is usually a reason people aren't bringing things to them.

Yeah its new about a month old now and yes does it with all three mags but ig you get the round chambered it shoots like a dream put both 17 round mags through it without a hicup but both first rounds chambered

[CementFinisher]

Myself and close Friends own M&Ps i have not found them to be ammo picky. I would try differrent mags, as stated above the feed lip could have gotten bent. Did you clean it when you bought it before firing it? the cosmoline can burn onto the slide rails and slow the slide enough to not cycle. also are you a new semi auto guy? I've seen this happen with guys limp wresting. If none of this works send it to them, smith has great customer service. Hope you didn't get a lemon, every company has them. good luck

[CementFinisher]

wait so your having a hard time chambering the first round? are you riding the slide forward?

[CementFinisher]

Maybe recoil rod and spring assembly. Your not seeing any metal shavings in the chamber are you? brass deformation?

Yeah my M&P40c is definitely not ammo finicky at all... I have fed it all sorts of ammo from cheap as dirt reloads to high end HPs... Never had any issues..

If it's that new, happening on all your mags and only on chambering I would venture a guess it might be shooter induced somehow...

The feed lips could be bad. Im not limp wristing it  and it happens by manualy dropping the slide and with the slide release. There was a video on youtube of the same thibg happening to another guys pistol ill try to post it up.

Im having same issue feels rough and im not holding on to the slide at all

[MadHatter]

If that's the case I would try a different mag, and if that doesn't do it I would send it back to S&W for repair. I am leaning towards a bad recoil spring from what you are describing. How's the feed ramp look? Is it nice and smooth or is it rough or maybe have a burr? Without seeing the gun and the malfunction myself all I can really do is speculate...

When you are chambiring a round are you manipulating the slide to the rear and then letting go of it? Or are you assisting it as in holding on to it as it slides forward?

Most if the times I have seen malfunctions from someone chambering the first round are from the operator assisting the slide forward.

I have put somewhere around #5000 rounds through a m&p 9mm and it ran flawlessly as long as I did my part correctly.

[elkslayer069]

Nope letting it go to operate like its designed to do sounds like i should just snd it back and be done with it

I would recommend that or giving them a call first.

everything I've found so far points toward the ejector.

Out of curiosity, what kind of ammunition is hanging up on you?  And to the comment saying M&Ps can be finicky... no.  M&Ps will eat anything a Glock, XD, Sig, FN or Ruger can eat.

M&P 9mm failure to feed
Here's my input:

The ejector isn't involved in the feeding process.  If your problem is the same as shown in this video , it is your extractor that is the issue.  There might be a burr (probably towards the bottom edge) on the extractor hook that is preventing it from sliding into the extractor groove on the case.  You should also look for an abnormal build up of gunk that might be contributing to the issue.

It should be an easy fix.  As long as you know how to use a punch, hammer and can punch out a roll pin, you shouldn't need a gunsmith.  You should remove the extractor and using a file or Dremel, remove any burrs or deformities on the extractor edges.  Don't round the inside edge of the 'hook'.  Only remove material that obviously shouldn't be there.

If you don't want to try that, I'm sure S&W would be happy to help you.  Personally, I would rather do the 5-10 minute job myself than wait several weeks.

This image shows what the extractor will look like removed.  I've never taken mine out before. There is probably a spring under decent tension underneath it, so be cautious.

Same problem as video federal ranger and target, hornady custom jhp, blaser brass, pmc bronze, and winchester white box all 115 gn

[CementFinisher]

The guy in the video is the problem not his gun. hitting the slide release or letting the slide go when fully back is how semi autos ar4e meant to be operated. With yours you said it does it when hitting the slide release i would definitly guess rough feed ramp or recoil rod spring assembly. Hope you get it fixed and back soon.

[elkslayer069]

Thanks fisherdave problem fixed took out the extractor it had tool marks in the claw on the bottom edge so i took them out with some emery cloth smoothed things up so i put back together and now  its eats everything just like before.

You are a good man!

M&P's CAN be finicky. I had one that would fail to fire (would dent the primer) and it would also fail to eject. This was isolated to a couple brands of ammo. I sent it back to S&W and they sent it back saying everything was "within spec". I took it out and still had issues so I sold it and bought an XD...problem solved 

[Austrian Hunter]

I have the M&P .45 and took it to the range for extensive testing last weekend.  I put about 500 rounds through it.  NO PROBLEM, I do have two complains!  I hate the night sights it comes with and the trigger.  The paint dot on the front sight disappeared slowly, by the time I was done it was all gone    But the gun shoot immensely accurate for that price, trigger, oh well I guess I can upgrade that anytime same with the site.

[CementFinisher]

glad someone here could help you out. I have many handguns but my M&P 45 has the most rounds 2050. All problem free. I am thinking of having it sent it and ran through. Guessing it should have a new recoil spring with that round count. I don't think the trigger is bad but its very different compared to many of my other guns. Is the trigger on par with my sigs no but those firearms function completely different.

[CementFinisher]

Austrian hunter im with yea on the sights, mine seem to be really faint aroind the 350 round mark. i always bring some cotton swabs to wipe them off.
