Does anyone know the weight of the MSH spring that comes in this kit? It's the kit with the 18.5 lb recoil spring, extra power fp spring , sear spring ect.

Wolff has standard rated at 30 lb.  Reduced at 24, 26, 28.  Link

The Wilson kit has some great reviews.  Might have to try myself.  OOS at WC.

After looking a little more at Wolff, seems to vary based on model and make.  Linked to Springfield, and Colt is completely different.

Maybe I confused things, and myself.  My Springfield had the locking mainspring housing, which has been replaced.  Gave you wrong numbers, probably should go with Colt data.

I like a 16lb recoil for hardball.   20lb main with factory ammo and a steel firing pin.

All these hard-ass springs these days are retarded.
