Does anyone know what weight recoils spring these little alloy frame guns use?

AFAI Remember, the BKS, BM, and the BKM all use the same Recoil Spring.
I don't remember a separate factory weight for the Alloy framed (K) guns, but I may be wrong.

Wolf lists their replacement Recoil Springs for the Model BM (only)
Factory @ 12#

https://www.gunsprings.com/STAR/BM ...r...: None Available Factory Standard.: 12 Lb.

About the best I can do..

added..
FWIW, Numrich lists the Recoil Spring for the Model BKM & BM as the same part number springs. However they list the recoil spring for the BKS as a DIFFERENT part number.

Jack First's Parts lists one spring as the same for the Models BKS, BKM and BM.
Neither gives a weight of the spring.

Confused Now...

Thanks, the rod inside the spring is slightly shorter on the alloy frame gun because the buttress in the alloy frame is thicker by about 3/16 of an inch. I got this as a bag of parts so figure I should replace the spring.
