Mainsprings

[John Sabato]

(No wisecracks Hugh and Frank!)unless the spring is too long and will not permit full use of the toggle. The issue is the appropriate amount of spring tension. Depending on the diameter of the spring wire used, and the manufactured diameter for the replacement spring, it could be longer or shorter and still work fine. Use a known good magazine for the testing. If you have more than one Luger and it is possible to switch cannon assemblies from the one that doesn't malfunction to the one that does would tell the tale about whether or not the mainspring is functional.


I would imagine that the only way to know what the appropriate amount of spring tension for maximum compression of the replacement spring is, would be to have access to engineering specifications from DWM or Mauser or one of the other manufacturers on replacement part springs.


How about it Patrick, got any details about original Whermacht specs on mainspring tension over there?
