M&P9 2.0 5” break in period and reliability issues?

M2.0 failure for slide to lock back

I am not sure if anyone else mentioned it... the manual states to lube the slide lock tab on the left side of the pistol. S&W added the spring loaded tab so that the slide would not release when a magazine is seated firmly. Lube it as per the manual and shoot it some more... have fun!

I have a 1.0 9c, 1.0 9 pro 5" and a 2.0 4.25" VTAC. All I have run thru them is 115gr, mostly Federal from Walmart and not had a single issue with any of them. As the others said, put 500 or so rounds thru it and see how it runs from there.

Just bought a 9mm 2.0 FDE 5" with safety.

I have an M&P 9mm Pro and a 40 Pro both 5" barrels. They are absolutely flawless and have shot everything I have fed them.

The 2.0 was having failure to feed issues. I was using Freedom Reman 9mm 115 and 124 grain HP and RN ammo. None of that seemed to matter as every few rounds it would not eject spent round and obviously a new round would cause a jam. I continued to shoot and finally decided to take it home and clean it again. Went back to range and it was better, but all of the sudden I got 5-6 in a row. Of course this could be attributed to many things as we all know. I cleaned one again and shot 200 rounds through it and it was better but still having the issue.

Called S&W and they suggested I sent it back; which I did. Could be a while before I hear anything back I'm sure.

I also bought the same gun but in 4.25 barrel with upgraded sights. I have not shot that yet but racked a couple mags by hand and it seemed a little stiff but it's new. So we will see what happens.

Overall I will say that I really like the gun, it's accurate and I like the way it feels. I felt it was easier to stay on target with faster pace firing.

Let us know what you find out. My 5" 2.0 started life with some of the same issues, then got better after a few 100 rounds. But lately, it's gotten worse again. Even with factory ammo, I get quite a few FTE's. I clean the gun every time I shoot it, and none of my other guns are having issues with the ammo I'm using (all 115gr).

Nice, good shooting gun, but all the failures are getting a little concerning.

Will do. I did also buy a M&P 9mm 2.0 4.25 FDE and it's shot perfectly right out of the case with not a single issue. (Shooting exact same ammo that I had issues with my 5" 2.0) Even stranger that the 2 guns are basically the same except the barrel length.

I have two of them and so far have run 700 rounds through each with no cleaning, just a little lube. All with either Speer Lawman or Federal American Eagle 124g. 0 issues.

In my opinion, and I know others will differ, but 115g remanufactured ammo in a brand new full size pistol is kinda asking for trouble.

Why would you say that?

Why would you say that?

What he probably means is that:
1) remanufactured ammo can tend to be loaded a little light to save on powder cost,
2) brand new guns can often benefit from a little breaking in, and
3) 5" guns have the heaviest slides so they need a little more shove to get moving.

"Trouble" in this case means the occasional stovepipe or failure to lock. Nothing catastrophic.

Will do.

Thanks. I loaded up some 115's with a different load (5.3gr Winchester Super Field) and those ran great through my 2.0. That's a load we used to shoot a lot, but found they are a bit snappy in smaller guns. We have been shooting 3.8 or 3.9gr of Clays lately. Works awesome in all of our guns, including my FS P320RX. Soft shooting and very accurate. But apparently the 5" 2.0 is a bit more picky about ammo, as it does not like the Remington 115gr Range Bucket bullets, either.
