Today I decided to give the gun a complete tear down, and check along with cleaning the barrel. Probably wasn’t one of my best moments, but I got a good look at the hammer and the grub screw inside used to adjust the hammer spring tension. Took my time realigning things, and went as far as to give the grub screw a complete turn out, and then back in. After everything was back in and I did some more fine tuning on the Huma regulator I just set it back to how it shipped to me and adjusted the hammer spring.

From all my tinkering I know I can make it fire over 900fps now if I wanted to, but I settled for it in the 870’s. Tonight after work I’m going to check how my groupings are now and hope for the best.
