When we were teenagers I helped a friend work on a Luger to reduce trigger pull. We worked all of the moving parts over with fine sharpening stones and accidentily ended up with a full auto Luger. I was standing behind him when he fired the first time. He had only five rounds in the clip and all of them emptied so fast he didn't realize it until he noticed that the action was locked open. I noticed immediately because several cases fell on me. No appreciable rise in the barrel during firing. We also found out later that taping tire weights to the barrel for "balance" restricted the movement enough to keep it from firing as a semi-automatic. Wonder what kids do today to learn about things.

Since I can think of now way the Luger's mechanism would go full-auto without slam-firing, I'd say you and your friend were pretty lucky the thing didn't blow up. Though I'll admit I'm a little surprised a Luger would slam-fire.
