Ejection Problems

I just purchased an M&P9 as my first pistol. Taking it to the range the other day, I discovered that it ejects at 12 o'clock, directly into my face. I've emailed S&W, but from reading some other posts, it sounds like they are closed at the moment. I'd like to know if this is something that requires me to send it away, or if I should bear with it until the gun is broken in.

Aside from (or should I say in spite of) the ejection issue, it has quickly become my favorite gun to shoot.

I'd put a few brands of ammo through it first, maybe try some SD ammo.

My 9FS had very weak ejection for the first hundred rounds or so, but after that it's been perfect.

It should come out of it after break in. Did you give it a cleaning like the manual says before shooting ?

Wearing a hat helps too.

Bear with me, I'm still new to the whole forum thing.

But yes, I did clean it fairly well before shooting. However, I don't know if I paid enough attention to the extractor area the first time. I've since cleaned it again, and made sure there was no gunk/crud around the extractor.

Hopefully I'll be able to hit the range tomorrow and reassess. Thanks for all the help!

Thanks everyone for telling me just to stick by it! I shot ~150 rounds through it today, and it functioned flawlessly!

Good for you. I always like to get a couple hundred break-in rounds through a new gun before I start worrying about the "small stuff".

I just shot my new VTAC 9mm today and noticed the poor ejection too.
Glad to hear this should clear up!

That was happening to me too, when I first shot my 45. The shells were ejecting into my face. I actually had one drop down my shirt.

we sent back our mp9 for the same issue, shell ejecting back and hitting my wife in the face.

We just got the gun back and guess what? exactly the same thing. I think the guns are tuned for rounds heavier than the 115g practice rounds that we shoot.

I just installed a wolff 15lb spring and recoil rod, and have a 14lb spring as backup, to see if that help the eject path at all.

I actually have a video of what is happening -

What does it do if you shoot it rather than your wife? Sometimes holding a bit tighter and pushing forward a bit stronger will solve this problem. Don't loosen the grip till after the gun has cycled completely.

x2. I've found the 40s will do this if the grip, wrists or arms get a little "spongy", firming up the support behind the gun makes it go away.

My problem was not cleaning the gun on the first use out of the box. After cleaning the gun of the factory lube, the gun operate normally now. Try to clean the gun throughly.

Case Ejection Problem

My 9mm M&P Pro was ejecting cases at 6 o'clock for the first 500 rounds. When I used up my ten boxes of CCI Blazer aluminum, I switched to CCI Blazer brass. The cases have been ejecting at 4 0'clock ever since.
