9mm/7.65 parts

Forgot to ask about moving the toggle assembly from one receiver to the other - any problems with ejection or loading, does bolt fit both 9mm and 7.65?

An answer to your question is yes you can. You have to remember that these handguns were all hand fitted as there were no CNC machines back then. That is why so many parts are numbered to the handgun. I own a DWM 1921 Alphabet Luger in 30 Luger caliber. I have fitted a 1939 rebarreled receiver to my frame, and have a complete Erfurt toggle train in it. This is in 9mm.

I am a handloader so I can tailor my ammo so that one mainspring can be used(9mm in my case) to fire both 30 luger and 9mm. The magazines are the same for both calibers.

One might get lucky and have a different complete 9mm upper fit on your 30 Luger lower/frame and function correctly, but don't bet a lot of money on it. Just know that it can and is being done.

Which main spring would it be possible to use with both 9mm and 7.65 and which main spring would not be advised to use with both. I have both 9mm barrel receiver and 7.65 barrel receiver but only the 7.65 bolt assembly/lower. All parts seem to work together but I have not done any shooting just working slide and dry firing. Everything seem to work smoothly...Am thinking of obtaining another bolt/toggle assembly?..........
