OP, congrats on your new Luger. She looks Nice! My opinion is to clean and lube it properly. They are plenty of videos to tell you how to do it. Plus be sure to read the FAQ section as there is a wealth of info there. Then go out and shoot at least two mags of ammo. Clean it and lube it up. Then enjoy it for what it is, a collectible Luger. Get a shooter grade Luger if you really want to shoot one regularly. That is what I did. I got a great shooter for $800 a few months ago. Actually I have two shooters now. I have two Lugers that are collectible and I want to keep them that way.
But, then the devil might just make me shoot those eventually.
