Just want to rant a little, been at this for 3 months now, have a lot of public interest for me to do this, in the home stretch for my FFL. You know what I have been doing for 3 months?? READING READING READING!!! WRITING!! STUDYING!! And not just the reading of the Penn Foster class material the real gunsmiths laugh at. I have bought 6 books written from 1930-1960 on the subject. I practice filing and hardening metals and stoning, (not on real triggers that's insane and unsafe). I haven't shot or handled any more then I have before I started this quest. Ya know what?? I love this!!!
