I believe someone in this forum correctly idendified the following German pistol often carried by German officers in WWII.

Deutsche Werke Akliengesellschaft Werk Erfurt.
Ortgies 7.65mm

I'm looking for a second magazine and cannot find anything with the name Ortgies sold by any US supplier. Anyone know of a possible source?

Check with Triple K. They used to manufacture magazines for just about any semi auto handgun made. Their website is a bit on the sparse side, but it is worth it to order the catalog. Last time I bought one I think it was about 10 bucks.
You may also try Numrich Gun Parts, I think their website is something like e-gunparts.com. The Ortgies is not that rare of a pistol, so hopefully you will be able to find one.

Thanks for your help, I'll check them out. I was hoping the Ortgies might be just a little less common but the gun shoots well and is still in good condition with the exception of the holster and unless it was going to a an extremely rare piece, I'll take the one that still shoots reliably. Thanks again.
