Interchangable toggles?
 

I have asked a dumb question about long and short frames. And now I have a question about toggel trains. Since then I have read a few more books from Lugedoc but still cann't seem to find the answer. Are all Luger toggle trains interchangable? Assume that they are correctly headspaced. And would the new Mauser toggels [1970s] work in a DMW? Thank You

A general answer to your question is yes, they are interchangeable. You can even put a new model toggle train in a 1900 if you make a relief in the receiver for the new model extractor. The difference in a long frame and a short frame is all forward of the takedown lever so it has no impact on the toggle train length. I have no idea if the new Mauser toggles will work in an original DWM. I suspect they would but I don't have any experience with the 1970's guns.

As Ron said above, Theoretically yes, but the length of the breech blocks can vary and will affect the headspacing. TH
