Sometime you don't even know you have a problem until you read a post on this forum. RE: Frizzen fit? Looked at my GPR today and found it looked exactly like the OP. Since I had shot and hunted it for at least 5 yrs. warranty was not in the options. So I tried a needle file. Frizzen is at least file hard so out comes dremel. Machinist blue on pan, close Frizzen, clamp spring, remove frizzen, lightly grind bluing off, polish with wet/dry, repeat about six times to get acceptable fit. Maybe an hour and a half, but now I don't have a problem I didn't know I didn't have before I read the post. Just a word to the wise be careful.
