Nice Shooter (noncollector) level Erfurt Luger.
The Luger was made in 1917 by Erfurt for use by the German Army in WWI. Original magazine would have been bottom slant cut nickel plated with a wooden magazine bottom.
It was later reworked by a German Police Armorer and used by the German Police After WWI and before and perhaps during WWI.
Later someone refinished it, the sear safety came off.
This gun has been refinished which delegates it to shooter grade (as opposed to Restored)
1. Magazine is Mauser made, WWII, not WWI as your Luger was a WWI issue.
2. Gun has been salt blued, original finish should be Rust blued with internals, inside of top of frame, mag well in the white steel, but I bet yours is blued.
3. Sear block should be in the white, yours is heat colored
4. Straw parts have been redone, way too dark
5. No paint in GESICHERT safety marking
6. Breech block has chip in it.
7. Top of receiver forks just ahead have only part of the original mill marks there, some of there have been buffed away.
8. Used to be a reworked Luger for German police issue, reference the last picture, top of sideplate has the sear safety cut out and the receiver has a hole drilled for the retaining rivet that is missing. Sear safety is gone too.
So you have a very nice Erfurt Shooter Luger with a Mauser magazine. Probably $800 IMO. (I restore Lugers for a living)

Shane, the Magazine was made by Mauser during the period 1936 (late m block) all the way up to German Army Lugers made in 1940. It is classified as a Type 2 ARMY Magazine. It was issued to another Luger that had the same serial number as the one numbered on the bottom of your magazine. The Eagle over 63 is an acceptance marking put on it by an inspector. So it was an Army Magazine, not a Police Magazine used in an Army Luger during WWII so yes it is a NAZI Army Magazine. Most Lugers dont have matching mags, the ones that do are rare and sometimes we see more Police Lugers having their matching mags because of the environment when the Luger was taken or found. In the Infantry setting, a captured Luger was separated from its magazine and emptied so the GIs did not get shot with it. Sometimes even the side plates were taken off too. Most times the mags never made it back to the original Luger, such is life. Your magazine is pretty standard so no big value there, perhaps $80 unless you can find someone that has a Luger in that time frame, same serial number including the lower letter suffix that is under the serial number on the frame front. BTW, a Luger, unless it has a working sear safety can be fired (I know, I've done it) with just the top section (the cannon) consisting of the barreled receiver and toggle train. The Police picked up on this and added the sear safety to prevent this during cleaning. Yours should still fire that way because the sear safety is gone. Please be extremely careful with your Luger. By the way, your pictures are EXCELLENT! A big help.

Prices and other info on my website at Thor's Luger Clinic (TLC) I dont round edges like most refinishers do, I also do the inside of the Luger. I have done over 300 of them. I have a very good parts guy and a master grip restorer and a person that is a master with magazines, including magazine bottom replacements that look exactly like the originals. I also use a master engraver if the proof/acceptance marks need touching up. Salt bluing, rust bluing, fire bluing, strawing, are all services I provide. I dont refinish, I restore.
