I found the trigger pull on my CZ455 too heavy and that it was causing inaccuracy. I removed the trigger spring and replaced it with a YoDave spring from the kit that they sell. It comes with 4 springs and I used the heaviest one of the four, in the interests of safety. The difference is incredible. I don't know what the trigger pull is now but it's so much lighter and makes the rifle so much more fun to shoot and definitely improves the accuracy for me.
It's not a difficult job to do, just a little bit tricky. You just have to follow the instructions (they can also be found on YouTube).
