CZ recoil, firing pin, and trigger return springs matched to competition loads and reduced-power configurations. Lighter recoil springs let your CZ cycle soft factory 9mm without short-stroking; heavier rates tame hot loads in Limited. Reduced-power hammer springs lower pull weight for Production and SSP divisions. All springs are spec'd for CZ 75, SP-01, Shadow 2, and compatible platforms. Tune your recoil system without guesswork. Fast same-day shipping on most orders at Shooters Connection.
