How brisk is the ejection? A dribbler out is too much spring for the ammo sometimes. A over zealous far far away ejection might be too little spring and may even mean broken ejectors later. Does the hold open lock EVERYTIME when there are no stove pipes. If no it might be too much spring. Failures to feed are a lot of times too weak a mag spring. Tom's advise on ejectors is well founded. Much move fully but still needs to have good spring pressure here too.

Ross, I/d be pleased to work on your luger. Sent details today via PM. Tom

Pushed the "Easy Button" and sent to LugerDoc.Got it back a couple weeks later. Gotta keep a firm grip, but shoots fine when you do.

Thanks Tom
