Great thread!
Please correct me if I am wrong, but I was given this information by a well-known German collector....maybe others here can reinforce what he told me. He said the German foot soldier was just given a rifle (Mauser) and no sidearm. The officers carried, or, were issued, .32's. NCO's carried the 9mm. He said that is why it was so difficult to find a Luger, etc. Unless you found a soldier who had picked a 9mm up or acquired one from other means, the only way to find a Luger/Walther was from a deceased/captured NCO.
Here is an AC41 P-38:
A rare 1939 Mauser Luger. Matching holster, tool, all matching SN gun including two matching magazines. I was also told that less than 3% of the Lugers today have 2 matching magazines....another side note.
A bit of extras....
