Hi:

Here is what has worked for me.

OAL with round nose bullets, start off at 1.173 inches. Fill your magazine with 8 rounds. If the Luger feeds the first and eighth cartridge the same way (manually), you are ok. If not, adjust all 8 cartridges shorter by 1/1000th steps until all 8 do feed properly. Now you are ready for reliable firing function.

As to charge, start low so that the pistol will not function. Go up 1/10th of a grain, in three shot groups, until full function is obtained. When full function is obtained (totally reliable feeding of 8 rounds from the magazine and proper hold open after the 8th round) you have obtained the right load for the set of springs your Luger has in it. Loading more than a few 10ths hotter than this basic load should begin to cause jams pretty quickly.

Now, that wasn't so hard after all.

Springs are really the key to healthy Luger function. Without proper weight springs, the timing of the action between the magazine spring and mainspring will be out of "tune" causing havoc to proper function.

Hopefully, someone will soon be making proper Luger springs.
