1921 Police Luger?
 

This is a pistol that I've just bought, which I think might be a police gun. I don't physically have it yet so these photos are all that I can post right now. What do the forum think? Does anyone know what the PMP on the left frame might mean?

John F,

Your Luger appears to be a police gun although the sear safety has been removed. The sideplate has been modified to clear the safety and the side of the receiver has the rivet hole where the safety would mount.
