Joe,
Let me advise you that repeatedly dry firing a Luger is NOT a recommended practice. As a pre-teen, I once was blessed to keep in my possession a DWM 1918 Luger that belonged to my uncle while his house was being repaired after a fire... I was allowed to keep it in my room and handle it as much as I wanted because my parents knew that I had no access to ammunition which was carefully locked away by my father... I just wasn't allowed to leave my room with it. I spent many many hours disassembling and reassembling that Luger... It wasn't pristine, but it was all matching... imagine my surprise when I disassembled it for the last time before be required to return it to my uncle to find that the very tip of the firing pin was no longer there... It had fatigued and broken off from repeatedly striking the back of the bolt face.
All in all, I probably dry fired that gun a few hundred times over the couple of months that I had it... It took a lot of allowance to replace that firing pin. The fact that it didn't match the serial numbers on the gun didn't matter to my uncle... only that it went boom if he had to use it to protect his family and property...
All that long story just to make the case that dry firing is not a good practice with Lugers... NEITHER is it a good practice with the Winchester Model 94... Don't ask me how I know...
