Bad extractor or bad ammo?

It's not dirty but I'll give it a good cleaning anyhow.
The extractor pin spring seems strong enough to do its job.
Even when a spent shell sticks in the tube it takes a tool to get it out so i'm pretty sure it's not the extractor.

Is it common with these to have the rear bore increased slightly to accommodate larger modern rounds?

Thanks for all the feedback.

Hi:

Are you telling us that after firing, you have to use a tool to forceably dislodge the stuck case; that the case is actually stuck to the chamber walls?!?

Your fired case doesn't look all that strange to me, actually it looks quite typical for 9mms in general.

I bet that if you were to replace that extractor spring, your Luger would extract just fine, as Lugers have a very positive and powerful extraction force. See U-Tube for a video on how to replace your extractor spring. Also, when the spring is in spec., it is quite hard to move the extractor by finger force.

As a general comment, any "normal" modern brass case should fit your chamber quite well. I would't be heading off to some "Gunsmith" with my precious Luger for "adjustment" of a design that was perfect upon conception over 100 years ago.

Enjoy shooting your Luger, but don't shoot the "hot stuff" through it.
