Failure to feed?

[bustedmp]

Had my wifes new M&P 9 out today so she could get used to it. Overall it worked pretty good for a new gun, but out of 50 rounds, it had 3 failure to feed malfunctions. I was using American Eagle 124grn FMJ. I really like it, and my wife is very happy with it. I was just wondering if the FTF was from it just being a new gun, or if it is an ammo issue.

More likely new. There can be little bits of crud left over from manufacturing that need to be run out of it, smoothed, etc by the initial shooting - once you get through that first few hundred rounds of ball, you should be ok. While I am not a fan of cleaning very often, you might feel better and help get the crud out of it if you wiped it out a bit now (SLIP 2000 - non-toxic, works like a champ), lube it up (SLIP EWL, same), run more ball through it (another 250 or so rounds), and give it another quick and dirty clean/wipe lube. (I am only suggesting what would otherwise be excessive cleaning because you had 3 FTF already and it might give you an advantage in break-in.) I would not expect it any more such malfunctions, and certainly not after another 100 or so rounds of ball, but get more down the pipe. Then the quick 'n' dirty clean (10 minutes worth from start to finish - really), lube the snot out of it, and you should easily go the appropriate 500 rounds of duty ammo testing without any malfunctions. If it won't go 500 consecutive rounds of duty ammo with only lube (no cleaning) there is something seriously wrong. (500 rounds of duty ammo is the suggested testing paradigm, and I have done it with my last two duty pistols, a 10-8 custom 1911 and a factory Gen4 Glock 21SF.)

I have had "fail to feed" issues with my .45. I called S&W and they sent me a new extractor, but I'm not convinced that is the problem. I also polished my chamber with Mother's polish.

The gun is feeding OK now. I have 870 rounds through my gun now. The last 170 have not had a failure.

Doug M. is correct, your gun should go at least 500 rounds without issue and without cleaning. In fact, I would say that it should make the 500 mark without any additional lube either.

Now, that is not to say you shouldn't clean your gun; you should. I clean mine after every trip to the range. I haven't done that with my M&P for the last 300 rounds or so, but that's because I'm testing it.

I sent my new M&P9 FS to S&W for repair, with similar issues.
I had 5 FTF's with the first magazine of Remington UMC flat nose. I switched to Federal American Eagle with no issues. The next mag of UMC had multiple FTF's. I finished the box of UMC with problems on each mag, and had one failure to eject on American Eagle.
I wouldn't have been concerned with a few issues as the gun was being broken in, but with over a dozen failures I didn't feel comfortable with it.
For what it's worth, their customer service was great.

Could be due to a number is issues.

Clean the gun and lube per the users manual. Make sure the ammo is properly seated in the magazine and try it again.

I've shot a wide variety of brands and loads through my 9mm FS with no issues, so I doubt it's the ammo.

The big question always is. Did you read the manual first,then clean and lube it before you shot it for the first time ?

was not expecting to hear any problems like this. I've put thousands of rounds through my M&P fs and do not recall ever having an FTF or FTE. Even new from the box it worked flawlessly from the git. Maybe a mag issue?

I've always had feeding issues with American Eagle. Not sure why. Winchester, Remington, Black Hills, Hornady never a problem. Go back to American Eagle....2-3% FTF or FTE. Go figure.

In police work they would call that a clue. That ammo must be out of spec in some way. One thing pretty generally true in 9mm is that ammo tending toward the hotter side seems to be the better choice.

As soon as I got it home from the shop I gave it a good cleaning and lube. I gave it a good cleaning when I got home, and used a light grease on the slide rails. The original cleaning and lube consisted of only frog lube. I must say that it was rather easy to remove the powder fouling from the bolt face and surrounding areas, but IZ suspect the frog lube just wasn't enough lube on the slide rails for a new gun. Took me a little while to get the copper residue from the barrel though, but I expected that for a new gun. Time will tell.

I clean my guns as soon as I get home from shooting them. It doesn't matter if I only fired 1 shot from them during a hunt, or several boxes at the range, they get cleaned.
