The stiffness of a gun frame will not change from hardness nor changing the steel from mild steel to chromoly, hard or soft.

The stiffness of steel is pretty much the same thru all the alloys and unchanged by hardness.


But by increasing the yield point of the steel the frame can take more displacement without plastic bending. And since spring rates go up with some power(d squared or d to the power of 1.5 etc...) of displacement and a higher yield point receiver can take more displacement it's spring rate is higher right before plastic failure that a "soft" frame.

I am glad to be here.
