1942 German Luger "Help!!!"

I inherited a German Luger from my grandfather who served in the Europe during WWII. I downloaded a sheet that would help me identify what exactly I have, but I don't know hardly anything about it. From what I have read, I see that it is common to find one with a mismatched serial number for the magazine. Well, the one that I have has all matching serial number including magazine, holster, and the little metal thing in the top of the holster. I was wondering if there is someone out there that can help me out with what it is I have and approximate price. I really appreciate any help. Thanks.
