I would like to mention that all of my modifications in no are permanent except for polishing metal surfaces and an over travel stop.
What I had found is that the hammer and the trigger sear are not correctly aligned and that there is excessive play.The pin holes are over sized which causes both to move at an angle rather then parallel to one another.This in my belief causes irregular pulls as the hammer or trigger may or may not make contact with the other metal surfaces adding friction sometimes and not other times.
So I pretty much did a complete tear down of the trigger group stoned all surfaces where they have a possibility to make contact.I then added shims to the hammer as well as the trigger to make sure they aligned as much as possible without side to side play.
Also had to find a better pin for the trigger as the factory pin play was terribly excessive. After the sears were polished I did lighten up the trigger spring as well as removed one coil from the secondary sear spring. I can add a spacer under the spring if needed to add weight.I only removed about 1/2 a mm.
I now have a 3.5lb trigger that breaks as clean as my Savage accu-trigger.The shims and stoning took 100% of the grittiness out. By adding the over travel stop there is about 1/16 inch or less travel after take up.
