Commerical 9mm

[HerrKaiser]

To answer your question about if your 5 digit s/n is a post war production, the answer depends on what its serial number is. 1-72000 were made before the war (I may be a thousand or 2 off there, but it was in the low 70,000's). After the war, they were still serialized with 5 digits until around 92000 at which point they numbered the commercial pistols in the "alphabet" style.
