My gunsmith put an oversized hinge pin in a 16ga 21 for me that was off face. I'm pretty sure the problem was from hook wear. Replacing the hinge pin isn't a big deal on a 21 according to my smith. The whole cost wasn't very much and I think he bought the hinge pin from Galazan. Maybe $100 a few yrs ago. The hinge pins on these guns aren't usually elaborately engraved like English guns and it's no big deal to replace as long as you have a good gunsmith who knows what he's doing. In this regard, I have NO idea why it is such a huge deal on these English guns, other than the engraving, and why it seems to cost an arm and a leg??
