My CZ 457 got down to under 16 oz just by adjusting trigger screws. By replacing the spring it is down to under a SAFE 8 oz. I ordered my spring from McMaster Carr website. The attached picture has the website address and spring order numbers and images of the factory spring and two of the different size springs I ordered.
The trigger pull adjustment for the CZ 452 ZKM is carried out after removal of the stock using the adjusting nut (Fig. 5).
