Since you have no takers so far, I went down to the safe house and dug out the M2.

Wire diameter .060" 14 coils. The pistol works flawlessly.
No way of knowing if the spring is original to the pistol.

I decided to compare with my BYF 41.

Wire diameter .059" 21 coils. Also works flawlessly.
Also don't know if that spring was ever changed.
