CZ 75B springs

Springs set how your CZ 75B feels and cycles: the double action and single action pull, the hammer strike, the reset and how the slide moves under recoil. Factory springs are heavier to work 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, Ultimate and DPM.

Spring kits

• Eemann Tech ultimate spring kit: 11 lb recoil spring, 9 lb main spring, competition trigger, firing pin and sear springs, a magazine catch release spring at -10 %, a trigger bar spring at -15 % and an extractor spring.
• Eemann Tech springs kit: trigger group and recoil springs in one kit.

Main springs and recoil springs

The main spring sets the hammer strike and the double action pull. A lighter one gives a lighter pull, but test ignition with your primers. 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. Zendl and Toni System recommend their lighter springs when you change a DA pistol to SA.
• Sear springs: standard or -10 %.
• Trigger bar springs: standard or -15 %.
• Firing pin springs: standard, light or weaker, and Ultimate springs for the original CZ firing pin or the Ultimate firing pin.
