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.
