I completely agree. I absolutely love doing my own work and hate when I can't.
I can't begin to describe the satisfaction I get, when I have one of my guns down to bare metal/frame/etc do my own polishing/trigger job/etc and reassembling.
I have taken the FCU completely down and back together, no problem at all.
I am stuck on the firing pin pin.
I cannot figure out what you could have used to get that pin out.
I have a 1/32 punch that looks and feels too big and have not wanted to do any damage with. That's the smallest punch I have (and in fact seen) and smallest drill bit I have.
Can you (or anyone else) show me what and how you used?
Thanks,
Doc
