I am wanting to swap out the plastic guide rod with a stainless steel one, but the problem I have run into is that the CZ store website says that it must be used with an aftermarket spring. OK, but they sell 17#, 18#, and 20# recoil springs. Does anyone know what the spring tension is on the spring that came with my gun. The spring that came with the gun is green.

Thanks for any help.
