Breech block not closing - Page 2

Nah, the mag problem is probably totally unrelated, I just didn't know about it as I haven't found it worth the effort to put a full mag in it until yesterday. The mag spring is very stiff so my theory is that the feed lips are too far apart, making the cartridges sit a bit too high up and cause excessive drag.

The mag is of unknown vintage (has a wooden bottom) and apperars to be in very good condition, but I'm going to experiment a bit with an aftermarket mag first. Previous experiences have taught me to always work on the cheapest part available.

What brand and weight of recoil spring did you install? Did you also change the firing pin spring? What ammo are you trying to shoot? Just a few things that come to mind first.

Our resident forum Luger mag expert...GT, can help you out on rebuilding that mag if necessary, and if it is a match to your Luger. GT has built me 2 mags from scratch for a couple of Lugers, and they are beautiful....both with wood bases.

I installed the std spring (38 lbs) from Wolff, together with the firing pin spring that came with it. I tried UMC and Winchester, but none would feed correctly. It just feels like the top cartridge is pushing too hard on the bottom of the breech block.

Does anybody know what a good spacing between the feed lips should be?

If anybody on this forum would know that measurement, it would be GT, as he is the Luger magazine expert. Send him a note. He is a very knowledgeable man, and will help you any way that he can....he is a true gentleman.
