It is the Weihrauch spring from my local RFD that won't fit the Steel and AA Tx spring guides?
I could just leave it but I don't like the amount of preload this spring has just to make 10 ft Lbs seems odd.
Yep, they used to be longer, softer springs. Extra preload means a softer shot cycle with less piston bounce which is why modern spring like the Titan seem so harsh to shoot. The original spring you now have should give a comfortable 11+fpe without being harsh, and a guide set will fit as long as you get the right one.
