CZ 13lb Recoil Spring

Fits: CZ, including the CZ-97B/BD, SP-01, Shadow, Shadow 2

Note: This is a light spring, and typically used in competition. The correct recoil spring is based on the ejection distance of an empty/fired case.  6-8 feet is the optimal ejection distance.  This can vary based on the recoil spring weight, bullet weight, slide weight, and powder charge.
