Extraction trouble

ithacaartist · 03-15-2012, 01:07 PM

Kyle,

Look at the fp's tip under magnification.

Also, you might want to check whether the front end of the pin is fluted, with 3 longitudinal grooves in the pin which would allow for the escape of pressure should a primer be pierced. Earlier models' fp's were not originally relieved, and sometimes replaced or reworked to establish the safer setup, which helps prevent the firing pin from being turned into a powerful gas piston when ignition pressure from a pierced primer could enter through the hole for the fp's tip in the front end of the breech block. In the case of your numbered, original pin, just obtain a good aftermarket one that is fluted, and swap it out for shooting. Tom Heller may have some; if not, they appear frequently at online sources, sellers, auctions, etc.

If the extractor system and firing pin system is all good to go, then the item that I would look at are the magazines. As I am sure you know, Lugers are very sensitive to all of the springs in them, and the mag feed lips. I think that you are on the right track. I own 2 lugers that will NOT function 100% with MecGar mags, even with the 10% stronger mag springs that I installed. The both seem happy with their originals and Stoeger(sp) mags. Every Luger is a challenge in itself.

I think your right there the extractor and firing pin look great, also it is an unfluted fp. I went and shot some WWB throught it today and no pierced primers in the 16 rounds I fired so Im hoping that was just a fluke with bad ammo. The mag is an original though not numbered to the gun but im starting to blame it. Next time I shoot it im gonna load a single round at a time in the mag and remove the mag before firing and see what happens. If it makes it through several mag fulls I'll figure its the mag. When I shot it today the first shot on both mags failed to extract then on the first mag it made it all the way through and the last round didnt extract. On the second mag it was every round. It always does it on the last round and almost always on the first. Hence me suspecting the mag.

It is not uncommon for the last round to not fully extract from the receiver, since there is no loaded cartridge below it in the mag assisting it. I belive this was discussed somewhere on this forum, but not positive on that. The mag follower is not a lot of help to the last expended piece of brass in ejecting. The extractor should extract it, but the process from there can be a problem. Those mag springs usually need to be quite stiff to help everything work.
