Ok, I was working on two HP's - a Browning and an FEG. I had to take the triggers out of both and everything went fine with the Browning. The FEG was another story - the trigger pin was very tough to get out and I managed to bung up the area aroung the pinhole with some scratches and hammer marks. My question is - can these be removed? Would it be really expensive - meaning professionally done on a milling machine - or is it something that can be done by hand with files if your'e willing to work at it?
