Cz 75 sp-01 mainspring

Has anyone tried replacing the mainspring for a SP-01 with a Tanfoglio Extreme main spring? I hear that it is shorter, but that would just reduced the weight. Can anyone confirm that this would/would not work?

Thanks

Short answer. No they are not interchangeable tanfo use a very short spring mounted sideways as there main spring and cz use a longer spring that runs up the back strap of the gun. Also length of a spring has nothing to do with the weight of the spring.

Thanks for the reply! I wasn't to sure as there is a lot of similarities between the two.
