P320 ejects casings back at my face

Hello all, first post here on Sig Talk, great forum you have here! I am new to handguns and just picked up a brand new SIG P320 compact, 9mm with night sights. I love everything about it so far except after putting my first 100 rounds through it (Federal 115g champion fmj) about half of the casings ejected back towards me, hitting my head, going over my head, to the left, hitting my shoulder, chest etc.

I might just not have my grip technique down yet, do you guys suggest just putting more rounds through it and seeing if it just needs to be broken in? I picked up some Winchester white box ammo too so I was going to see if that works better. Appreciate any feedback, thanks.

Here's a pic of my new p320:

Hello from a fellow CT-er.

I also have a P320C, but never had any brass ejected back to my head. Shot a lot of different ammo. Try some other ones like the WWB etc. and see if it persists. If it does, perhaps call Sig Customer Service ago if and they could probably replace.

It's a fabulous gun.

The major player in your problem is probably week extractor tension.
I doubt it's the ejector.

Does it happen only on the last round ?

Thanks for the replies guys. No, it happens from the beginning of the magazine. The slide does lock back after the last round however. Here is a video of me firing about 40 rounds:

In my experience, guns eject at different angles with different people and their grips. Mrs. Flash has had a couple of guns that ejected in her face but went over my shoulder when I shot it.

Unless you're a reloader, your best bet is a different brand of ammo.

My FNX9 did that a lot especially with weak loads. Mostly due to very stiff recoil spring that has loosened with use. Try something like Speer Lawman 124gr and see if it eases up. Should improve over time...unless your grip is too week and interfering with the recoil cycle.

Howdie Chuck.

Have 3-5 other people shoot your pistol.
1. If they get the same results, contact Sig immediately.
2. If some shoot it and some get proper ejection to the side while others do not, that's a tougher nut to crack. What's the difference between the people who get proper and improper ejection? I myself would still call Sig.

I suggest having a greater sample size of people shoot your pistol so as to not jump to conclusions.

My wife and I just watched your video and I noticed something the second time around. Is your grip a teacup grip? In other words, are you setting your pistol and right hand mostly on top of your left hand? If so, your left hand is not helping hold the pistol DOWN against the lift force generated by the recoil. If you can grip the pistol with your left hand wrapped horizontally around your right hand, your left hand will help hold the pistol down much more and possibly help the casings eject to the side much more. Get more people to shoot it, especially experienced shooters with a strong horizontal weak/off hand grip.

Also, remember 70% of the grip on the pistol should be from your off/weak hand while only 30% should come from your strong/trigger hand.

Finally, I've shot all different kinds of ammo through mine and they all work the properly. And they SHOULD all work the same - properly. I won't have a pistol that must be fed a specific type of ammo. They are designed to work properly with any decent factory SAAMI ammo.

A last thought - if others shoot your pistol with proper ejection, consider taking lessons from a good instructor and get your grip corrected.

Update

I went back to the range today and put another hundred or so rounds of the Winchester white box 115g through it with my father. He is a more experienced shooter although more with long guns. I worked on my grip and it was ejecting casings perfectly. Every single one that I can recall went sideways like it's supposed to.

At the end I had a few of the Federal champions left and loaded them separately, I didn't really notice but my father said the casings were going more backward than with the Winchesters. I certainly didn't have any hit me like last time.

I will keep trying different kinds of ammo, working on my grip and practicing trigger pulls as I seem to be hitting the target a little lower than where I'm aiming. I hope this ejection issue is behind me, thanks for your input . Here is some video: https://vid.me/rD8A

Bridgeport is less expensive, but the best is Wooster Mountain, outdoor range in Danbury. $15 all day, extra 5 for the target frame. Gotta wait for better weather though.

Wanted to give an update, put another ~150 rounds of Winchester white box 115g FMJ through it yesterday at the range, casings continued ejecting properly. I have over 350 rounds through it at this point and besides the first 100 ejecting the brass backward, there have been no failures or other issues. I'm loving this thing!

P320 ejects casings back at my face

Wanted to post an update in case anyone reads this and it could help them:

After almost a month of owning the p320c I've been going to the range a lot and have since put about 1000 rounds through it. Despite my first time with the brass ejecting back toward me, I have not had the issue since correcting my grip. In fact I have not had a single FTE, FTF, stovepipe, jam etc in those 1000 rounds using cheap range ammo (mostly wwb). I hope this won't give me a false sense of confidence as this is my first experience with a modern striker fired pistol. My buddy bought a VP9 at the same time and although he hasn't fired it quite as much, he has had 3 jams. I am very impressed with the P320 and have zero regrets, it's fun to shoot, dead reliable and accurate.
