Fast Ed,
The "limp-wristing" aspect of the dynamic has entirely to do with the direction of the muzzle at the moment the second round discharges. The action either functions completely and properly, "resets itself", or it doesn't; it sounds like, in your case, it does.
The "double" discharge rate of a Luger is pretty dam' fast, if you weren't expecting it you might not believe you heard two rounds.
As far as the magazine not emptying completely, a sticky sear bar or disconnect could be an element of the problem, thus ceasing fire when pressure on the trigger is released.
Frankly, it is not every gunsmith who can be trusted to work on a Luger. They are uncommon pistols, whose mechanical function--particularly the trigger linkage--is unusual. Gunsmiths who are not actively familiar with Lugers may not be able to fix a problem or, worse, may cause problems due to their unfamiliarity.
I strongly recommend that you give some thought to sending your Luger to a known expert in their care and repair, Tom Heller aka Lugerdoc. The odds of a proper diagnosis and repair will increase dramatically. If you do this, be sure to send both magazines along to determine how much they are part of the problem.
Good luck.
