The Ultimate spring range was developed by Eric Grauffel and his team to improve your shooting sensation. These springs are ideal for shooting in competition, they will guarantee lightness and performance.

Trigger spring for CZ 75 Shadow 2 and CZ 75 SP-01 Shadow. Each spring (sear or trigger) will provide a 15% reduction in weight compared to the original spring.

The tests are carried out on a Shadow 2 factory weapon. On 10 weighings, the highest and the lowest are removed. The average is carried out on the eight remaining weighings.
