I thought I'd give a final update on this topic/thread. I probably have another 1000 - 1500 rounds fired at the range with zero issues. I'm still shooting some of that "troublesome" Freedom Ammo also with zero issues as well. Looks like the #15 lb hammer spring was the right call for my P-01. Super happy with my CGW Pro Package and thankful to their efforts to help me solve the issues I had. Thanks to everyone here as well!
