what is the spare spring with the CZ shadow?

[jsdboy]

Hi, i am not getting any answers from CZ, and my dealer doesn't know; thought i would try here.
just received my new CZ SP-01 Shadow, and it came with this nice shiny spring in the box. it is not the recoil spring.
different weight hammer spring?
does anybody have an idea what this mystery spring is all about?
thanks.

It is a different weight hammer spring. get the lowered one, Frank at 2Aplha has them.
