Commander 9MM extraction problem???

My 9MM commander is having a problem with extracting a spent case from the barrel. About once in every 2-3 mags full the extracter comes off the spent case while the next round is trying to feed from the magazine. It appears to me the slide is moving too fast and the empty isn't is not out of the way before the next round tried to feed from the mag.

Do I need to speeded up the side or slow it down? And how do I do it? I asiume ot will have something to do with the recoil spring.

Have you adjusted the tension of the extractor?

^^^

Also check the hook, make sure it's 90* or less.

Just to clarify, the empty case is in the chamber, the nose of the next round in the magazine is being pressed against the the empty case, and the base of the new cartridge is in contact with the breechface and not ahead of the extractor. Is this correct?

Another thing to check on the extractor is whether or not the hook is riding up the case bevel when the pistol is in battery. Another way of determining this is by removing the slide, slipping a round under the extractor, and pushing the cartridge back against the breechface. The base of the cartridge should be able to be pushed back flush against the breechface with no contact between the extractor hook and the case bevel.

Combined with other factors such as tension, hook depth, and deflection this could result in the symptom you describe.

If you want to slow down the slide, fit a flat bottom firing pin stop from EGW or Harrison and replace the mainspring (hammer spring) with a heavier than standard (23lb) Wolff.

Check the ejector length. Because of the spacer at back of most 9mm magazines, the ejector must be long enough to eject the empty before the disconnector rail moves back past the cartridge in the magazine. If the cartridge in the magazine moves up before ejection it can push the empty up above the ejector.

Aggravating feeding and extraction issues are usually solved with a unique extractor design. Brownells carries them the, Millenium Custom II-1911 Advanced Competion Extractor. It's been around many years, orginally, called the Aftec Extractor. Aftec sold their design to another parts company and hence the more convoluted part name.
But, the small springs apply the pressure to the cartridge's rim in a different, but consistent pressure. They work and eliminates trying to find the correct bend in the extractor, getting the correct bevel on the claw, messing the extractor. They are expensive, but they are a one time fix, I my experience. I use them in my 1911's chambered in calibers other than 45acp.

Extractors.....

When a 1911 9mm gun fires, and the empty stays in the chamber and doesn't extract, it may be caused by different issues...…

One possible issue: If the mag feed lips are too wide, it will allow the top round to sit higher up than most mags if the mag sits high in the frame. If the slide of a gun sits higher on the rails than other guns, using a mag with wide feed lips may allow the top round being stripped to contact the bottom edge of the case trying to be "extracted." This will leave the empty in the chamber and the extractor will be forced out of the extractor groove of the fired case...….

Second possible issue: The 1911 9mm needs a longer extended ejector than a .38 super or .40. I use a 9mm ejector that measures 1.30" from the nose to the back of the ejector.....which is essential for optimal function when using 9mm magazines with a spacer. The added spacer requires a full length extended ejector like Colt engineers designed in the 1911 Colt 9mm guns.

Third possible issue: Extractor tension is too light and/or the claw needs fine tuning to properly hold the case while extracting the fired brass.

I use 1911 and STI 2011 9mm guns for competitive action shooting.....I seldom if ever have a problem or jam, and if I do, it is most likely a problem with the ammo that I somehow overlooked......

I’ve read of the earlier ejection need in the 9mm 1911 for quite some time. Typically cited, the feeding round kicks the brass off the extractor is the typical reason for the jams in the shorter ejector guns. Maybe I missed it, but t never read this very simply stated additional reason for it. Thank you.

Problem Update:
Replaced the extractor with a Ed Brown extractor. Off to the range with 100 rounds of reloaded ammo. Using different magazine one without the spacer in the back of the mag. Loads were 124 gr JHP and 5.5 grains Power Pistol powder. Went througn 80 rounds with zero problems, so I'm thinking I've got the problem licked. Then one failure in the mag containing rounds 81 through 90, same problem on 87th round. One failure in mag containing rounds 91 trhrugh 100, same problem on round 93.

So, I'm still having the problem. Next thing I will check is to see if I have a rough chamber aince the problem surfaces shooting 80-100 rounds. Maybe carbon builds up making the round stick in the chamber long enough for the extractor to pull off the round.

9mm Commander ejection issues....?

So what is the length of your extended ejector from the front nose to the back....? If it is too short, you will continue to have issues......
