My thoughts
if you choose to clean and fire it, whats the odds of a numbered part breaking? It's not like a number matching papered Luger that would suffer a massive hit in value if you threw a round in it and broke a toggle link or damaged another numbered part, trust me, their aren't many parts that aren't numbered.
It ain't no virgin I'm sure, the Albanians already fired it and showed it horrors you could never dream of, it could probably scare you with stories, more so than you scare it by firing it... it's not like a new rifle and besides.. grease is cheap.
But...... if one chooses not to fire it, big whoop, I have a few weapons I have never fired, probably never will. Out of 3 Albanians, I have fired 1.. the other 2, I don't worry with shooting, my jollies get taken out on a mismatchy ugly one. Do I need to shoot the other 2, for what, to check function, with dummy rounds it feeds and ejects, the pin is free and the hammer drops.. by all rights they should work.
Call me a conflicted collector
I'm a buy 2.....or more of something, especially if I like it.. one to shoot, the other, or others are usually really nice example, hand picked that gets tucked away. An example...like a papered bring back matching Luger and a mismatchy if I break it, oh well, slap a part in it and fix it, commercial shooter Luger..
