Factory triggers are often designed for one purpose.. To let the rifle manufacturers lawyers sleep well at night!
In other words HEAVY! Most factory triggers can be lightened up and the creep greatly reduced. Depending on the model i can usually get them safely down to around 2 Lb. This involves stripping the trigger assembly down and re-stoning the mating surfaces to achieve a better sear geometry and less friction on the sear surfaces. Often a new spring is installed and then the trigger is re-assembled and fine tuned for the correct weight of pull.
