Default 5” Performance Center... does this look normal?

Took my brand new 5” Performance Center 9 out today to run its first rounds thru it. Ran 170 flawless rounds thru it. Smooth and easy to shoot, very nice trigger.
After shooting I stripped it down to clean again and check it out. I found a lot of marks on the top of the barrel, more than I would expect to see after 170 rounds. It actually has a groove that catches your finger nail if you run it down the top of the barrel.
It’s hard to see in the pictures.

Does this look normal??

Nope... that does not.

Bluing loss is normal, but not scoring. And being at the muzzle end where barrel and slide lockup affects accuracy, I'd contact S&W customer service send it back to S&W on their dime.

I've had 2 M&P's with over a thousand rounds through each, and nothing more that very minor bluing loss (rub marks) has occurred.

I would say that's not at all normal. I dug out my 5" M&P Pro stock barrel, which has ~3000 rnds through it, for comparison.

Pardon the fingerprint... couldn't see it 'till I got the pic up on the computer screen.

Thanks for the quick replies. It doesn't seem normal to me, so I thought that I would tap the experience here at S&W forum.
I will contact S&W.

Does it have a sharp edge/burr inside the slide ?

There is a lip inside the slide. It appears to have been machined that way.

I'll add to the others and say no, that's not normal, especially with a groove that you can feel. I assume you cleaned and lubed your M&P before you shot it. The factory preservative oil that comes with the gun is not a good lubricant. If you did clean and lube it first, and followed S&W's somewhat minimalist lubrication recommendations, you may have under-lubricated a tight new pistol. I like to slightly over-lubricate new pistols for at least the first couple of shooting sessions. Nevertheless, if you lubricated the barrel at all, it should not have ended up looking like that.

Below is a photo of the barrel from my 1.0 M&P 40 compact. It has 13,000 rounds on it, and shows no such wear. I'd say S&W owes you a new barrel and possibly a new slide, too.

My 5” ported core barrel still looks smooth after a few hundred rounds. As others suggested, you may have some kind of burr inside the muzzle end of the slide. Even my 4.25” barrel with 1500 (or so) rounds is still smooth like the ones above.

Keep us informed please.

Is the muzzle of your slide smooth inside or does it have a lip around it?

swsig, yes cleaned and lubed prior to first shots.

My shield 9 has 1500 or so thru it with virtually no visible wear.

Update: Emailed S&W about my barrel. Sent them some clear pictures of it. I will post them here also, they are better then the originals that are in my original post.
So S&W replies: We reviewed the photos, it appears to be simple cosmetic marks. Thank you for contacting S&W, glad we were able to assist you.
Regards, XXXXX

I must say that I was almost speechless after reading the reply.
So I replied: Simple cosmetic marks?? Really?? I have 2 other S&W pistols with over 1000 rounds thru each and neither have more than the slightest rub mark.
This new $700 firearm came out of the “Performance Center”, and after 170 rounds the barrel has chattered scrapes that catch your fingernail when rubbed along the barrel and you say “simple cosmetic marks”. I feel that S&W should inspect it and figure out what caused the marks. What’s the barrel gonna look like after a 1000 rounds.
Regards,

Now I wait for a reply.

Did you clean and lubricate it before firing the rounds? How about during the firing session?

Yes. Cleaned and lubed prior to firing the first round.
No. Not during the 170 round session.

The pictures are clear to me. The end of the barrel don't look good in the photos. I would think another barrel would do the same thing. It looks like the slide would could be the problem? Hard lockup?

Just a guess.
Looks like you've got a ported barrel. I seem to remember reading about certain types of ammo that shouldn't be used in guns with ported barrels, and sometimes bullet plating would go through the port. Maybe one of the problems was bits of bullet plating blowing through the ports and being abrasive.
Good luck..

Don't email... if the reply comes back no joy, call them and talk to a live person and be adamant about the there being an actual groove in the barrel surface. It's clearly evident by the pics you posted.

It kind of looks like flame erosion... could there be a problem with the gas leakage from the ports?

The location of the grove looks like where the rear of the barrel bushing is at when the slide is forward and locked in battery... what does the rear surfaces of the bushing looks like?

That email reply is pure Bravo Sierra.

Did you register the gun with S&W so they have you as the original owner? I have a PC Shield in 45 and if my barrel looked like that I’d be pretty disappointed and asking to speak with a CS supervisor. With the steels today there is no reason for that, they should be sending you a shipping label and taking good care of you.

Yes I did register it.
S&W replied again, this time with a return form to fill out for a shipping label. Also said 8-10 week turn around time. That is disheartening, to be without my new pistol for possibly 2 1/2 months.
Believe me, I am extremely disappointed with the situation.
I will call on Monday and request to speak with a QC supervisor.
Thanks for the replies.

I would be surprised if once they have the pieces in hand and see what you have they don’t expedite your handgun repair.
Write a nice detailed letter explaining your dissatisfaction with your purchase and let them know the outdoor range season is coming to a close rapidly. Put the letter in with the handgun. Give them some time to make it right, if they fail time wise to get the pistol back to you then call and talk to a supervisor. I understand your frustration but stuff happens, give S&W an opportunity to make it right, I’ll bet they do.

Good catch right here. Do you have anymore info on the ammo that you speak of?

Tsb3 and I seem to have something in common here. This is the barrel of my M&P9 PC 5" after a couple hundred rounds; yes, cleaned and oiled BEFORE round one...





I actually thought this was supposed to be normal.

I also have a Shield 9 with well over 2000 rounds through it without even any wear in the bluing. How many calls to customer service might it take before they perceive a recurring issue?

Stetto that looks very similar to mine. Definitely don't think that it is right. Imagine how badly chewed up the barrel would be after a 1000 rounds.
I have a Shield 9 with 1500+ thru it, and like you said, barely even a mark in the bluing.
Mines going back. S&W sent me a return label, can't wait to hear what they have to say.

Does your slide have a machined lip around the inside at the muzzle?

Yes it does. Is that not standard for the model?

FedEx has my PC 5" taking it back to S&W. Anxious to see what they do or say.

You are absolutely correct about giving S&W a chance to make it right. I purchased a PC 1911 full size and lost the extractor at an outdoor match. I only have 400 rounds through it. I contacted CS and they gave me a 2 day air shipping label, they said 6-8 weeks turn around time. I told them I had a match in 6 weeks and they had it back to me in 4. I was impressed! The only thing I failed to do was remove the optic from the slide prior to shipping, they re-installed it but the elevation was way off by 6 inches when I got it back. I don't know how that happened lol. But a big shout out to S&W customer service and warranty department.

Can you post a picture?

I bought a 5" ported CORE slide kit for my 1.0 The slide is marked 9L. There is no lip inside the slide. The barrel does "swell" a bit but so does the stock barrel.

I would be glad to attempt a picture, but it is currently in the hands of S&W. Tracking shows that they signed for it on Tuesday.

I got a FedEx label yesterday, but the nearest shipping hub I can ship a firearm from is over 60 miles from me, and I'm not going that way soon.

The downside of being rural....

Yes. I'm taking mine to FedEx tomorrow, but have time for a couple more pics.

From inside:



From the business end:



I can neither see nor feel any wear on the lip itself, but it can be the only surface with a chance of contact, yes?
If bullet residue were an issue would it not affect both the machined lip AND the barrel?

I guess we'll find out.

It pays to READ, not skim, the S&W direction sheet for shipping.

They'll be picking my M&P up today, saving me 120 miles and 3 hours of my day....

This is what my new ported barrel looks like after the first 300 rds, I did clean and lubricate before firing the first time. Is this something I should also be concerned about?

It's normal. I have a factory ported barrel with over 1200 rounds, and a Wilson Combat barrel with over 300 rounds for Production Optics. They both have the same marks. The Wilson Combat one is actually marked up with the cutout of the ports from the slide. The wear will stop after a while, and you'll feel it's smooth.

Stainless Steel barrels look worse for wear because they don't really have a finish like the Shield barrels or the regular M&P offerings. There's nothing to worry about.

Mine does not look normal, SS or no. I read nowhere in the S&W literature saying I may experience and odd, increasing wear to the barrel that would eventually stop and become smooth again. At over $800 new, what do you suppose resale or trade in value becomes with a barrel looking like someone twisted it in 00 steel wool and scored it with a jewelry file?

Stainless Steel barrels look worse for wear because they don't really have a finish like the Shield barrels or the regular M&P offerings. There's nothing to worry about.
I don't believe my barrel wear is normal. It has a groove around the top half of the barrel that catches your fingernail when rubbed along the barrel.

You believe what you want. You asked a question, and I'm answering your question with my experience. I have two barrels, one being the factory barrel with 10 times the use yours has, and an aftermarket one with twice the use yours has. They both function as they should, with no malfunctions, and the wear stops and smooths out if you just keep using it.

Mine does not look normal, SS or no. I read nowhere in the S&W literature saying I may experience and odd, increasing wear to the barrel that would eventually stop and become smooth again. At over $800 new, what do you suppose resale or trade in value becomes with a barrel looking like someone twisted it in 00 steel wool and scored it with a jewelry file?
If you're getting into guns with resale value in mind, I suggest looking at Glocks or Colts. M&Ps have never held good resale value, even Performance Center models. I'm saying it smooths out based on my experience, and the pictures I just posted. If you don't trust the weapon and want to get rid of it, that's fine. But based on what I've seen and used, the wear is normal, and you just need to keep using it.

Your barrels do look fine. Neither has a groove worn into them, as does mine. That groove is my primary concern.

Question for ya: Did you see any difference between that Wilson barrel and the factory barrel? Besides the lack of porting.

I do NOT have resale in mind. I have never sold any firearm I've ever purchased. But it is a legitimate purchase point for many. The price of this particular model surpasses by a third the most I ever intended to pay for ANY handgun. So far, with minor issues that are being addressed, it's been worth every cent.

I'm also not dismissing your experience, but that is your experience, and mine is that I've never had a semi-auto, including my S&W nitride barreled models, develop any wear at all, much less like this. The ring at the end of the barrel corresponds with the shimming at the end of the slide, and my fingernail catches on it. I cannot think of any argument that will convince me that wear that deep is going to "smooth out" from continued firing.

It looks like S&W made a change from the 1.0 to 2.0 in the barrel/slide lockup.

Here's my 1.0 ported barrel. Notice that the diameter increases towards the muzzle. Two different angles. Somewhere around 600 rounds.

Next is my Storm Lake unported barrel. Note the increased diameter also. Not sure why it's so much longer that the OEM one. About 100 rounds.

So my slide, at the muzzle has no ridge. The same is true for my FS and Compact (both 1.0).

Good luck..


Good catch right here. Do you have anymore info on the ammo that you speak of?
The chatter I hear is about lead bullets and plated bullets. However for everyone that says "don't shoot lead/plated bullets with a ported barrel", another says "I do all the time with no issue" (or something to that effect).

Just make sure when you clean your barrel, you look for any residue, debris, etc., in the ports.

When I needed to return a very early production example E Series 1911 TA pistol to S&W some years back they sent me a shipping label to their Fedex acct. and had Fedex pick up the pistol from my home.

No need to travel at all.

I believe the problem with shooting plated bullets through ported barrels lies in the possibility of plating material shavings being ejected through the ports possibly resulting in injury.

IIRC, plated Berry bullets and others have a warning on their boxes that they shouldn’t be fired in ported barrels.

BTW: my M&P barrels, each with several thousand rounds through them, have become smoothly polished from use, but not scored. (.40 and 9mm)

That is interesting. Thanks for posting those pictures.

Any word? I got receipt confirmation on the 19th.

I called S&W on Monday. The lady looked it up and told me that they have not inspected it yet. She said probably 6-8 more weeks before they get to it.

Thats a very hot, dirty and hostile environment inside the slide at that location, especially if the barrel is ported. I would imagine that's why they characterized what they saw in the photos as "normal".

UPDATE: I received an email from FedEx today stating that I have a package coming on Monday which requires an adult signature. So, I called S&W. The very nice lady told me that they completed the work on my gun and it was soon to be shipped out. I asked if she could tell me what was done to it. She said they “repaired“ the barrel, not replaced. Interesting. Also interesting is, when I called to check the status about 10 days agoI was told 6-8 weeks.
I am glad it’s soon to be home and I hope that the “repaired” barrel is all good.

Please follow-up with your pistol accuracy next time you shoot it.

I understand your concern about the wear marks on the barrel but the most important question that did not get asked is how accurate your pistol was. Nice finish is nice but accuracy is final.

Interesting. I received the same email fifty minutes ago. No other contact, simply said they shipped it and would need a signature when it arrived on Monday.

I'm also interested in pursuant accuracy: The CT ct1500 had been torqued on to where I was afraid of stripping the hex nuts or wrench breaking the seal, so it was left on the firearm. Changing the battery will be a challenge, no doubt....
