eerw,
I end up with a new Wolf 13lb hammer spring cut down to 1.170 OAL and my trigger is just about 5 3/4LB DA. I have shot about 300 rounds with Winchester small pistol primers and not one single miss fire yet.
The stacking is still there but the DA is so light now, it does not bother me that much anymore.
Anyhow, I just wanted to share my experience in doing this so hopefully it could help someone else as well.
Thanks,
Sandro
