metric return spring length

I know the external spring length should not be less than 19 inches, anyone know the length of the internal spring? The external spring length in mine is 19-3/4 inches, two questions, what is the length of a new(external and internal) and does the 19-3/4 inch spring still have some life left in it?


Thanks to all!

The "inner" recoil spring is generally one inch shorter than the "outer".

A new set of Recoil springs measured 20" and 19", so I would say your 19 3/4" spring is good to go a few more thousand cycles.
