Just picked up a new Pedersoli Kentucky flinter from Cabela's. It's my first firearm purchase in my entire 43 (or so) years. It's a pretty thang to be sure. The flint, however, seems a bit too close to the frizzen at half-cock/frizzen closed, as the frizzen doesn't close completely. I assume I need to knapp it down a little, but I need a very basic lesson in doing this. Any suggestions? I'm dying to touch this beauty off! :-)
