All depends on the luger and the magazines. I have an artillery that shoots almost anything through it, and have had other lugers that were jam-omatics.
Just remember, if you use something to defend for your life, the papers will say "Nazi Luger used in Gun store shooting"
Doesn't mean that if I had a nice reliable one that i wouldn't do as you're saying. heck I have a pre-WW2 PP as a carry piece, same thing could be said about me. So, i will go be quiet
