A Savage trigger isn't all that hard to work on.It's actually pretty easy. I just had one come in today for a trigger job and it now breaks at a smooth and crisp 2.25 pounds.

If the person working on the trigger is able to stone through the hardeness of the parts then they really shouldn't be doing trigger jobs. All that is needed is a very light stoning to even out the imperfections that cause the gritty feel with a fine ceramic rod then followed up with a buffing wheel and polishing compound at very high speeds. So little material is removed that you shouldn't come close to breaking through the hardness of the parts.

Heck you don't even need to take the trigger all the way apart to do it.
