Dear w2ec:

Let's solve this problem right now.

Hugh is definately on the right track!

Remove the Wolff Spring and put it away (hopefully, forever). Replace it with the original spring.

Load the following please.

With your Winchester brass and round nose 93 grain bullets, the final OAL of the loaded cartridge must be 1.173 inches, as shorter will contribute to jaming.

Medium slow powder is best for any Luger load, 9mm or 7.65mm. For me, Alliant Power Pistol at about 5.4 to 5.6 grains is an advanced target load (three touching out of three at 25 yards). Load a full magazine of 8 cartridges, as they shouldn't jam now.

The jam you have shown us in the photos can be caused by too weak of ammo, or, too strong of ammo, as in the later instance, the breach block recoils faster than the mag spring's ability to properly deliver the next cartridge in line. You should be shooting from the Meg-Gar mags youv'e purchased.
