Luger stovepiping issues.
 

Ok so I'm having the same issue with just one of my lugers, a 1941 which I believe is force matched.

I use WW 9mm, a new mec-gar mag (and any mag, really), and my shells look like they have that very distinctive triangle on it after ejecting. I also get quite a bit of brass shavings throughout my pistol. Is it the ejector spring, or should I start there? I had 3 or 4 stove-pipes over the weekend in one day. I also had a double fire lol.

1. The double fire is an issue with your trigger, disconnector, and/or sear mechanism. DO NOT LOAD OR FIRE THAT GUN AGAIN UNTIL A COMPETENT LUGER GUNSMITH HAS REMEDIED THAT SITUATION. There are a few people on here who can help you with that, most notably Tom Heller (Lugerdoc here on the forum).
2. I would also recommend you make this a new thread so as not to hijack this one.

I'm not really hijacking; I too have an issue with stove-piping that isn't an ammo issue

Even so, you're likely to have more replies if you start a new thread and post pictures of your Luger. :)

Yes, unfortunately you are.
Start a new thread, or else this one will get hopelessly mixed up between the problems of two different lugers.

Threads are cheap = free!;)

Created a new thread for this discussion.

-The ejector does not have a spring; it IS a spring. The flat blade that protrudes into the bolt may
be damaged.
-The extractor does have a spring, and the spring or condition of the extractor could be a contributing factor
-The ding usually has nothing to do with a stovepipe jam, such are usually a result of the magazine or of weak ammo or too strong a recoil spring; resulting in incomplete recoil.
- brass shaving is not normal, and could result from several issues - from magazine to barrel
ramp cut and probably others
-the doubling, is likely not related to the stove pipe; but due to minimal contact at the sear interface, or a weak sear bar spring
-try other ammo than the WW white box, it is normally "good"; but not necessarily for all lugers.
I'd try some 124 grain ammo and see if your result is different- but AFTER correcting the doubling!

If you have more than one luger, try swapping the uppers from one frame to the other and see if anything changes.

This could be a long journey, as you have more than one issue causing different problems.

Don's reply has excellent info and gives a lot of things to look at. I would add on the double tap, sometimes people file down the sear protrusion on the firing pin or make other adjustments to the trigger/transfer lever/sideplate/sear bar spring/sear bar in an attempt to perform a 'trigger job" and decrease trigger pull. I suggest carefully inspect all those components, it is most helpful to have a separate properly operating pistol as a reference.

If someone tried to do a "trigger job" on this Luger, they may well have replaced, or cut, the std. trigger return spring.....this can allow bump firing. A Luger is not normally an easy weapon to bump fire, but soft trigger return spring and "hot" 9mm ammo can lead to it.

Alright alright. I know some places don't like duplicate threads on the same subjects, or they'll have responses with "no need to start a new thread. use the search function"

If you can, photos of the brass shavings, cartridges, and interior of the pistol might help.

I apologize guys, a kind mod made this thread for me. I have the one I'll be posting on here:

I recommend different ammunition....and a different magazine to see if that helps.
I have always been happy with Haenel mags for function.

Limpwristing?
 

Lugers as well as other autoloading pistols need to be firmly grasped when shooting or stovepiping can result.
