Hey guys,
Just wanted to get the consensus of other's that may have already done a Biro pen spring job on their cz 455 to lighten the trigger pull, is it worth while doing?
I've seen videos of how to do it and it looks relatively simple, I do have the necessary tools required; pin punches etc.
Or that being said should I try adjusting the factory trigger first and see how that goes? there's a nut you can turn in the trigger spring to increase or lighten trigger pull.
