Ruger Number 1 trigger job..
I do remember that someone offered a spring replacement for the Number 1 that did help with trigger pull. I think it may have been Wolf. You can check Brownells to see if they carry replacement/upgrade parts for the trigger group. I watched a video of disassembling the Number 1 action and I know that I would not do it myself. In my opinion rifle/pistol triggers are like brakes on a car/truck, they MUST work perfectly everytime.
