Springs set how your CZ 75 SP-01 Shadow feels and cycles: the trigger pull, the hammer strike, the reset and how the slide moves under recoil. Lighter springs let you tune the pistol to your ammunition, and complete kits turn a factory pistol into a competition setup without permanent changes. You can choose springs from Eemann Tech, Toni System, Zendl, KMR and DPM.
