I had an issue kinda like this about 4 years ago . It was on a VHE #1 frame 12 gauge . I eventually got the gun apart and it turned out the forend lug was cracking from the barrels . This was a gun we'd gotten from Jerry Amos 40 years ago and I had shot quite a bit . Seems to me I'd always had issue with getting the forend on blah blah blah . Anyway I sent it to Giacamo (I'm sure my spelling is incorrect) and they reset the lug on the barrels and blued them in a fashion that would be similar to what was original and shipped it back , think it cost me $500ish .
