Default M&P 2.0 9mm FTE

This is the first failure of any kind for my full size 2.0. I was at the range shooting WWB 9mm 115gr. I had 4 FTE's while shooting thru a box of 100 rounds.
In all 4 occurrences, the empty shell did not get pulled from the chamber, and the next round was pushed up against it. I had to drop the magazine and rack the slide back and then it ejected. This happened 3 times with my factory mags, and once with a Promag.
Before this, I've never had any issues. Is this an ammo problem? It was the only ammo I brought with me. I've shot several different brands/grains and they all fed and ejected fine.
If not the ammo, then where do I begin? Just doing a quick visual, I don't see anything wrong. Any suggestions?

WWB is rated a 1150 fps with a 115g bullet, that's a pretty light recoiling load. Try running a couple of magazine's worth using a "death" grip on the gun. Yes it's unrealistic and yes your hands will ache after shooting a mag's worth, but it will take out any limp wristing concerns. If you end up with no FTE's then, it's a combination of light recoil, fairly new springs and your grip absorbing some of that weak recoil.

Since your other ammo worked well, it's not purely a gun, magazine or grip issue so long as the ammo you used had enough oomph.

I had that happen in my Shield with the same stuff. Picked up a box that was on sale to try it out and about every other mag I got a FTE. I know it's the ammo because my gun runs perfectly on the the other types I usually use. I decided the white box would make good training ammo as it would introduce malfunctions somewhat regularly but randomly.

This is a typical result from "plinking rounds" One should expect to have some sort of failure when using ammo such as this. I use Federal and WWB and have had small failures however, when I use"Duty" style ammo NEVER have I experienced any failures. Your m&p is running properly the ammo is the issue.

Have you checked to see if there is a carbon buildup behind the extractor hook? This doesn't get looked at by most people.

Hopefully it is the ammo. And I'll check the extractor for carbon build up

Fired 250 rounds of Fed 115gr and Aguila 124gr with no issues. Must have been the WWB ammo.

Another 200 rounds fired without issues. I gave it a good cleaning and out of curiosity (after reading the previous replies) I scraped along the inside of the extractor with a small screwdriver. Even though I didn't see anything, I did find a good bit of carbon on the inside edge. That buildup could have been a problem. I'll make sure I make that part of my cleanings from now on. I also did the same on my carry gun.
