So i went with the safety pin spring. I haven't found any other models localy to replace the factory trigger spring.
I also did a nice deburr/polish job on all the trigger group parts and *housing* ( not where sharp edges are required as well

).
I removed the loose between the parts using brass shims.
The result is : creeeeep but the break and pull are great with the safety pin and polish job, I would say around 1 to 1.5 pounds.
There is a big improvement with the trigger job, hte only thing i can complain is the creep.
I tested it today. I was cold so i shot only a couples of rounds.
I like the improvements i made to the stock, it feels good !
First time i try SK Match in it. I can do better but its not bad... The rifle sure can shoot !
I finally tested the single shot adaptor i made.
I will have to make another one. The rounds jam when you feed them.
I think the angle of the round is too much, it will have to be more level with the bore.
