Is this a real Luger or a knock off? (It looks too good.)

[Sealgair]

I've always wanted a Luger, but the prices always prevented me. Yesterday, I saw this Luger on consignment at a local shop and was blown away. Not only was it in my price range, but it looked near-new! I spent all last night researching the few markings I could read, and by this morning was comfortable enough to jump.

It appears to be an incredibly good condition early commercial Luger, but I was hoping that some of you could confirm that it's even real and not some kind of knock off. The barrel is pristine! Mirror finish and sharp rifling! The finish looked so good I originally thought it may have been re-done, but all the markings are stamped into it, and there's no sign of new finish "flowing" into them. All the parts appear to match! No letter suffixes on the serial number! The only "blemish" is the import marks, which are obviously cut into the finish. (Blast them!)

If my research is correct, this should be a late 1910s commercial (Crown/N) pistol, but it looks fantastic, too good in fact. I'm wondering if I hit gold or got taken! Any help, opinion, or outright conjecture would be greatly appreciated!

Photos attached (which actually look worse than reality) and thanks in advance!
