I have three P7s in that S/N range (from 32504 to 54250). They are all date code IB, making them 1981 production. I'm guessing yours has the date code somewhere. See my FAQ here:
Hokey religions and ancient weapons are no match for a good blaster at your side, kid.
Whoa guys SO SORRY for the apparent tone of my response!! I typed it quick last night and didn't read it over before i hit the post button!
The tone sounds like I am being a nasty prick! LOL. I appreciate youre responses...I certainly didny want to sound that way, Jeez...
I'm going now to check my gun more closely:)
Thank you, Gents!
Per the list, still say 1982!!!
The BWB (Bundesamt für Wehrtechnik und Beschaffung or Federal Bureau of Military Technical Procurement) proofed guns for the military and police alike. That is the Batman looking symbol on your gun. It takes the place of the date code, Bundesadler (federal eagle), nitrocellulose "N" and traditional stag horn mark of the Ulm proof house found on P7s. NDS is just an abreviation for the state of Niedersachsen (Lower Saxony) where your police gun was carried.
Your best bet is to date your gun based off of the serial number, as a few have done above.
