Like DonVoigt said the ejector is a spring. If allowed it bents inwards, it's the tip working in it's proper channel in the breech that forces it straight. An image (even a lousy one hopefully) is worth a thousand words:

2 ejectors.

The extractor look to be all there, and in good shape. Can't comment on the spring tension.

I agree the extractor looks alright. I think the culprit may be the ejector.

I suspect the inside leg to be broken or very worn out.

I've marked where I think the problem is.

Thanks kurusu and all,
posting foto with open and close toggle,
it's actually not bad, though not perfect like on kurusu' pics, (those looks like brand new))
There is some visual effect that makes that not flush expression, but it's all straight when closed.
but technically is not absolutely flush, but this little deep is same along all length of leaf spring, I'd say almost perfectly flush in the middle.

I'll prepare and try to make new good photos.
So I'll go step by step to troubleshoot,

Right Side Opened click here
Right Side Closed toggle click here

Extractor from inside click here

Thanks

Your ejector seems to be alright.

The problem is somewhere else.

If possible get a new magazine. You will have to follow the tests DonVoigt recommended and then report back.

PS. The 2 ejectors in the picture are new. They are spares that I keep just in case. :rolleyes:

DonVoigt 05-09-2016 09:32 AM

Mario,
please post the pictures on the server here.
Some of us don't use the outside links. The pictures will also eventually disappear if hosted elsewhere and thus the thread will lose its value.

This may look like a stupid question.. but, have you cleaned the chamber well? Even my most trusted shooter will frown at me if I neglect cleaning it after more than 300 rounds.

mario17 05-09-2016 11:02 PM

Hi Kurusu,
I gave it to shmith, he made field strip clean and exam, said it's save to shoot to try, I shoot like 25 rounds.
It was 2 weeks ago when I was fresh Luger carrier and just got it.

I still not completely undestand how extractor works, saw this video bit strange, looks like brass pushed forward and then bounced out
, or maybe it's just not perfect case.
Luger high speed P08 slow motion 1000fps XLMoby(c)

I plan now do complete detailing, probably ultrasonic and will try another mag.
Thanks again for all your help.

* I will put pic on server, didn't know about this feature.

Best
Mario

DonVoigt 05-10-2016 12:05 AM

I don't think the luger in that slow motion is working correctly!

The EXTRACTOR pulls the cartridge from the chamber, it is the piece top center of the bolt.

It is the EJECTOR that strikes the bottom of the cartridge and forces it up and out of the action.

In that picture it does not look like the extractor is holding the shell long enough for the ejector to strike it, but that it just "finds" its way up and out from the residual gas in the chamber/bbl.

JMHO.

I agree. It appears to flip 180 degrees before exiting, as well! Why would anyone post this crazy video?

This one is better. https://www.youtube.com/watch?v=ZrrMe_Y9zy8

This animation shows it "by the book". https://www.youtube.com/watch?v=-DZ-DnTI_A8

That is why I suspected the ejector. Since the round is drawn from the chamber, the extractor appears to do its job, but the ejector should launch the case out, assised by the upward motion of the next cartridge in the magazine.

You may want to look at the extractor spring also. A small coil spring underneath the extractor. If it is too weak it will also cause ejection problems. I remember having a parts luger that managed to extract the cases, but would violently bounce them against the innards of the pistol before it was pushed out by the next round/magazine. All cases had a small dent on one side. The cases that did manage to eject usually ended up agains my forehead, in my collar or at other uncomfortable places. After replacing the extractor spring, the ejected cased went straight up and over my head, as they should do.

Hi all again,
I did another round of cleaning, and used other mag from expert who said this mag should work OK and got pretty much same result.

and after last shot with super hard hand I don't have toggle locked up, so I plan to change main spring.
Already made tool for change,
Can anybody recommend good place to buy new spring, I assume it should be new, no need to buy W2 era one. (?)

THanks
Mario

Wolff Gun Springs is the best source for high quality springs, outside of oem.
https://www.gunsprings.com They have several different springs for Lugers.

I buy most of my springs for my various guns from the them.

DonVoigt 05-27-2016 08:24 AM

How many different brands/weights of ammo have you tried?

There is an item in the FAQ that will help you select the correct replacement spring. It lists the spring specification for each of the variations of Lugers.

We already recommended that you check how hard the toggle is hitting the back of the receiver by putting some masking tape at the rear of the receiver.

Have you checked the small leaf spring that holds down the hold-open?

mario17 05-28-2016 12:31 AM

tx all,
tried
115, 124 FMJ Fiochi
and
Fiocchi Shooting Dynamics Ammunition 9mm Luger 158 Grain Full Metal Jacket Subsonic Box of 50
and
Winchester PDX1 Defender Ammunition 9mm Luger 147 Grain Bonded Jacketed Hollow Point

DonVoigt 05-28-2016 08:36 AM

Well,
don't expect sub sonic or 147 gr to work.

Try some 115 gr winchester white box, S&B, Magtech or brass Blazer.

I have had good success with all.

Fiocchi is hit or miss.

Edward Tinker 05-28-2016 10:30 AM

skip, skip, down, didn't read anything else

So, lets ask, who is Smith?

Not use FMJ - why?

Use one mag - why?

Sounds like you're limiting yourself for reasons I can't figure out...

Ammo underpower - ammo overpowered - its a fine line, +P is crazy - underpowered will cause problems.

The different weights will cause issues with slowing the toggle and upping the pressures - but not always making the gun work different. I think you need to settle on a few normal rounds, like winchester white box and remington - pick one FMJ and see how it works. Or is it you are not really in California and can't just pick up ammo of your choosing?

a magazine can be a major problem, but not firing FMJ, what are you wanting this pistol to do?

mario17 05-31-2016 01:46 AM

Thanks Edward, and all again.

Yes, I think main question is <what are you wanting this pistol to do>, I plan to keep it save for future generations, and won't make it my shooting pistole.
I just explore it a bit, it's my first arm + I like to have everything in order, or at least know what is wrong .

I'm very comfortable now with all choices, I will probably will retry single shot with recommended ammo, maybe will buy new spring , and then keep it box.

Best
