Brand new M&p 9mm Pro Failure to feed
After cleaning my brand new out of the box M&P 9mm Pro as directed by the manual, I took it to the range and fired 50 rounds of Blazer Brass and 50 of Monarch 9mm Luger. Fifteen to twenty percent of the Blazer rounds failed to feed and forty or more percent of the Monarch rounds failed to feed. This happened with two different shooters. Is this normal for a new gun or did I get a Dud? Should I try another box of ammo or send it back to S&w to fix it?
Thanks for your help!

Sometimes, the mags may be the culprit..clean them ? Welcome to the Forum

I did not take the mags apart to clean them but I wiped them with cleaner and wiped clean. Should I take them apart and clean that way? Both magazines were used when the misfeeds happened. Both mags were brand new too.

Can't hurt if your comfortable doing it, at least you'll know that it isn't a magazine issue. You can inspect, wipe down the body, springs and followers. I wouldn't use any solvents or oils on them, just wipe'em down. Hopefully, it's a simple fix. Could be just a break in period? You stated that you lubed per manual instructions, so she should run clean. Switch your ammo types to Hollow points, 20 round box of Federal..have another shooter try the firearm.. maybe then start thinking that it could be more complicated. Good Luck!!

Just did a little Google searching:
From another site...
I think you'll find the more you shoot it, the less that will happen. When New My wifes FS9 wouldn't feed those Red tipped Hornadys worth a hoot. (gun was cleaned & Lubed prior). Now 100's of rds later it will feed/Cycle any kind of ammo. I think the slide tolerances & Spring rates when new are iffy for some ammo. Once broken in it becomes a fire breathing, Jacketed Lead spitting dragon that very rarely ever has a glitch of any kind...
Thanks, all. I went back yesterday and shot a box of WWB 115 grain, a box of American 115, and a box of Federal Hydra-Shok 115 hollow points. Not a failure to feed with any of them - I am feeling much better, needless to say. This pistol is a real pleasure to shoot, very accurate and recoil is minimal.

Maybe it just needed some brake in although my FS pro 9 was flawless out of the box from day one with duty ammo and 400 rounds of target rounds . They sure are sweet shooters that's for sure , I shoot it the best out of all my handguns
EDIT: I take that back haven't made it to the range with my Black Friday Shield 9 yet but that pro is going to be hard to beat !

My first 300 rounds of WWB NATO (124gr +P) were flawless. it is possible that with lighter, 115 gr rounds you need to break her in for smooth operation...

guns are tools and not appliances IMHO there should be absolutely no break in needed. I will never buy a plastic gun until Smith fixes their quality control. If mine or my families bacon is on the line I would expect this firearm to work.

I have to agree here, there shouldn't HAVE to be a break in period with a firearm. But, seems like some do need it to start working reliably.
Guess I've been fortunate, as my new Ruger SR1911 and SD9VE both were fine out of the box. I'd like to include my M&P 45 to that list, but it was lightly used (from all appearances) when I bought it from the LGS. But it too, has been issue free.
If you read enough reviews, you find issues with almost all things mechanical, not just firearms. Hope you get things sorted out, a shame it happened on the Pro model.

Thanks everyone for your help. I found a video on YouTube that shows what my gun is doing. I don't think this guy actually shot his gun but would probably have had the same results
I did. He sent his back to S&W who put a new extractor on and solved his problem. I think I'll do the same.

I've had two M&ps. One was a full sized .45 issued by the police department I worked for. I notice right away at the pistol range that the .45 wsn't nearly s accurate as the H&K USP I hd previously been issued. However, it just felt so good.
The second is a M&P 40 CORE. It has really come into it's own since I installed the APEX trigger and fired a thousand rounds.
In contrast, I purchased a CZ75B Retro, and it was a tack driver right out of the box.

RE: the video...
If you ease the slide forward this can happen. The slide does not need any help. It should be pulled fully to the rear and let go. What I tell my students is to try to rip the slide off the back of the gun. This way you'll never retard the motion which can cause the failure to feed you saw in the video.
If your gun does this while firing, that is a completely different issue. My 45 had this issue and replacing the extractor seems to have fixed it. At least I haven't had a single issue, since the extractor was replaced, in over 2,000 rounds.

Mine does this no matter how hard and far you pull the slide back. The bullets get stuck the same way when firing.

Just curious does your extractor have any play in it ?
I'm wondering if that could be causing you issues . I have a M&P 40 , pro 9 and a shield . All have a pretty tight extractor except for my 40 it had a little play out of the box from day one . I've got about 200 rounds threw it and it has been flawless and even called S&W anyway to make sure all was good . They said if it wasn't excessive and didn't have any issues it should be fine . So anyway I'm just wondering if yours could be excessively loose causing the issue your having .
Also is it happening with all magazines ? That could be the culprit .

It doesn't seem loose. It happened with both mags that came with the gun.
I've also noticed that the slide lock engages without being touched when racking the slide.

The slide shouldn't lock back without hitting the slide lock/stop .
"unless " there's a empty mag inserted in the gun then it should stay open until released . Although there probably will be a time or two the slide won't stay open after shooting your last round that shouldn't be a big concern it can happen .Again though the slide should not stay open when pulled back with no magazine "unless you engage the slide stop" at least from my experience .

Man, right out of the box issues? Well, I have had that with a couple of other guns before, but not much. Hang in there and let the factory figure it out for you...just because the gun is brand new and all. Good luck.

Yes, this is very frustrating.
Does it fail to feed on every round or just the last round of the mag? First round of the mag?

About every third or fourth round fired.

Here's what I did...
First, I noticed that it could be the extractor. When the round would hang up, I could press on the back of the extractor and sometime it would go into battery. So, I suspected the extractor. I called S&W and discussed it with them. The tech on the phone agreed to ship me a new extractor free of charge.
When it came in, I installed it and polished the chamber with some Mother's polish. From the moment I polished the chamber and installed the new extractor, I haven't had a single issue.
It costs nothing to call S&W and hear what they have to say. You could also keep running rounds through it to see if it smooths out. It shouldn't need that, but you never know.

I've seen this same thing happen with a few different issues. One being the breech face and the other being different aspects of the extractor itself.
1. The breech face requires some "break in". I have on occasion helped the process along by running a wire wheel on a Dremel over the edges/corners of the breech face (i.e. the edges/walls where the case rim fits between).
2/3/4. The extractor pressure is too high. This can be caused by a spring, too much bend in the extractor, or... the extractor lip is either too shallow, not chamfered enough in the right places (there are two edges that usually need it), or simply a rough cut by the CNC that unfortunately made it passed QA.
In my opinion the quick fix is indeed a replacement extractor, but you could spend the time at the range just working through it.
As for the comment about these types of machines working 100% right out of the box, although I too would expect that every unit that leaves the factory should work flawlessly, the reason they only cost $600 instead of $1000 or more is that the manufacturing processes have been streamlined for efficiency which translates to cost reductions. If they need to test fire each unit and troubleshoot, the cost will go up. Presumably the number of units that need additional work is likely very low. Those numbers are likely so low that there isn't enough justification via lost revenues to add extra in house process to eliminate the failure rate. It's just more cost effective to handle the one off repairs and replacements. I understand the frustration, but from a business perspective, I can't fault them.

I got my gun back from Smith and Wesson this week. The extractor was replaced and the barrel was modified. I took it to the range today and the problem is solved no failure to feed.
Thanks for all your help!

Hit the "edit" button. On that page there is a "delete" option until someone posts a response (like I just did ).
