I bought acouple of the wilson spring sets the other day, mainly because the hammer spring was alittle lighter than the Wolff. I installed them and they're doing great.
I put a set in my wife's sp101 and it's like a new gun. Compared to the way it was , it's like having a trigger/ action job.
I had already done alittle polishing on the action of my Vaquero but the springs made it better.
