CZ Shadow 2 springs

Springs set how your CZ Shadow 2 feels and cycles: the trigger pull weight, the hammer strike, the reset and how the slide moves under recoil. Factory springs are heavier to work reliably with all ammunition. Lighter springs let you tune the pistol to your ammunition and your shooting. You can choose springs from Eemann Tech, Toni System, Zendl, KMR and DPM.

Main springs and recoil springs

The main spring, or hammer spring, sets the hammer strike and the double action pull. A lighter main spring gives a lighter pull, but test ignition with your primers before a match. Toni System recommends a weaker firing pin spring together with its weaker main spring. The Eemann Tech calibration pack has main springs of 7, 8, 9, 10 and 13 lb.

The recoil spring sets how the slide cycles. The Eemann Tech recoil spring comes from 7 to 13 lb for CZ 75 pistols with a long guide rod, and the calibration pack has 9, 10, 11 and 12 lb springs. Toni System also makes a recoil spring.

Trigger group springs

• Trigger springs: standard from Eemann Tech, lighter from Zendl and Toni System, -15 % or +10 % from Eemann Tech. A lighter spring lightens the pull, a stronger one gives a more positive reset.
• Sear springs: standard from Zendl and Eemann Tech, -10 % from Eemann Tech.
• Trigger bar springs: standard or -15 % from Eemann Tech.
• Firing pin springs: standard or light from Eemann Tech and weaker from Toni System.

Other springs

You can also get extractor springs for 9x19 and 9x21, standard or +10 %, magazine catch release springs, standard or -10 %, safety detent plunger springs and the right safety detent plunger from KMR, and an Eemann Tech magazine spring for MEC-GAR 19 round magazines.

Frequently asked questions

Will a lighter main spring cause misfires?

Yes, it can with hard primers. Test ignition with your ammunition before a match. A weaker firing pin spring helps avoid malfunctions.

The Eemann Tech ultimate competition kit. It has springs in several weights and the key drop-in parts, including a short reset disconnector and an extended firing pin.

Do these springs fit the TS 2?

Most do. Springs with the TS 2 in their name fit the TS 2 as well as the Shadow 2.
