SIG ejection issue

Hi guys,
I posted in the autoloader forum about an issue I'm having with my SIG. I was hoping someone over here might be able to advise me too. It's kind of hard to explain so please bear with me.

Suppose you have a 9mm P-226 in your hand. You've just had a failure to fire (or are "simulating one" or unloading the pistol) so you are clearing the malfunction by yanking back on the slide, which will eject the defective round in the chamber and strip a fresh round off the magazine.

On my SIG, when I do that, the unfired round doesn't eject. It is extracted fine but then it's like the round (Win WB 115 grain FMJ) is too long. When the casing is pulled back against the extractor it starts to fling the round out but it can't because the bullet is still in the rear of the chamber. The loaded round then is either somehow bounced around until gets ejected (about half the time) or it falls back down in the breech (about half the time).
The gun has fed, fired, and ejected flawlessly for the 150 or so rounds that I have shot through it. Technically, it does pretty much "work".
So you might be wondering "Well if it works, what are you complaining about?"

I'm concerned that in the unlikely event that I had to use it to defend myself and I had a malfunction (even more unlikely), I could end up just getting my gun jammed more by trying to clear it. Also, I'm just not satisfied with a SIG that you have to turn upside down and shake when you want to unload it.

So I am wondering if anyone else has seen something like this. Could it be that maybe the wrong ejector or extractor got installed or that a part is defective? Others have said that they use WWB without issue and I have personally shot thousands of rounds of the stuff in many calibers, most of it being 9mm so I don't think that there is any reason that a CPO SIG shouldn't work with it. I'd be extremely disappointed if that was the case.

If there is an issue I'd like to get it fixed soon. I'll probably end up sending it back for repairs but any ideas or advice would be really helpful.

I don't think there is an issue. If you're unloading, then you'd drop the magazine first, and the loaded round from the chamber would fall down the magazine well out the bottom of the gun. I don't know of any handgun that will eject a loaded round as forcefully as an empty case.

I always empty my loaded chambers by removing the mag, grasping the slide with my fingertips below the ejection port and the base of my palm on the left side of the slide; cupping the ejection port. I then turn the pistol on it's side with the ejection port down and pull the slide all the way to the rear in a slow steady motion. The round just falls out into the palm of the hand grasping the slide. Is it possible that you weren't pulling the slide all the way to the rear?

Take your question over to SIG Forum (http://sigforum.com/eve/ubb.x?a=cfrm&s=674608412). Maybe those folks can help. A malfunction clearance is supposed to work.

Asknight - Trust me on this, I was really cycling that action. It's not just that its not ejecting forcefully - quite the opposite. It is ejecting so forcefully that it is leaving gouges on the round coming out of the chamber when the bullet smacks into the rear of the chamber.

I usually unload the same way you do. The problem is that I have always been taught that the first thing you do with a malfunction is slap the mag, then reach up and cycle another round.
You do that with my SIG and you run a 50/50 chance of causing yet another malfunction. IIRC, SAAMI specs for the 9mm are around 1.169". Mine doesn't like anything over 1.120" or so.

I also checked with the guys on the SIG forum so hopefully someone knows something.

Recently there was a thread concerning cupping your hand over the ejection port and what happens to your hand when the ejector mistakenly hits the primer--OUCH. The pictures were graphic.

1. I would expect your SIG to work. Meaning it should eject live rounds.

2. Protect your hand and just let any live rounds you are ejecting hit the ground. Don't try to catch them with a cupped hand.

The rounds should go out the ejection port. The round should never fall down the magazine well. If it falls down the magazine well then you have an extractor issue that needs to be corrected. The extractor should retain the case against the breechface until it reaches the ejector and it should then leave via the ejection port. OAL is not the issue here. Your Sig should eject anything short enough to fit in the magazine.

Send the gun to Sig. The gun could fail to extract pretty catastrophically by jamming an empty case into the feed lips of the magazine. It is critical that the gun not rely on the magazine to prevent the case from falling into the magazine well.

Thank you. It will be going back to SIG this week.
I bought a SIG CPO because I figured I wouldn't have to deal with issues from SIG.
Just goes to show you that most any manufacturer is asleep at the wheel when it comes to QC anymore.
But at least they sent me a shipping label and are making the inconvenience to me as small as possible.
