In addition, by your description your gun shows the P proofs on cylinder and left frame which were not applied in those locations until late 1943.

You don‘t mention any topstrap property stamping. If there isn‘t one, the gun was most likely a DSC contract gun shipped to a civilian end user, and it‘s less likely that the military holster you have came with it from the war.
