Ben welcome to the forum.
Don't mind Jerry, but also be nicer and have a thicker skin, plus patience. I doubt you'll get much better posts anywhere else, except possibly at Jan Still's forum (and I moderate there to, so...)
I simply have not had time this weekend and I am sure it is the same as others. Many folks could not "top" Bobs response so they figure why try.
The resident expert and one of the best to ask about holsters is Jerry (people from all over the world have him fix their holsters to as new), so... You might notice that your magazine pouch on it has a different "skin", it appears to be pig, while the rest is cow hide.
The sear safety was installed after 1934, and quit being put on in the 1940's. Yours does not appear to have received a magazine safety (many police guns do not have these, but many do).
Your luger is interesting to me (I collect police lugers), it has mauser era proofs with the DWM toggle and the suffix is towards the end that they put DWM toggles on those lugers...
