I am using a 12.5# recoil spring in my STI and I'm getting very little buff wear. I have checked to see if the spring compresses on the guide all the way and it does. I am using the blue Wlison buffs.
I am thinking of trying a 11# spring
Should I expect to feel/see anything different by dropping a pound on the spring?
Also, who sells the Hiett buffs?
