As everyone points out, Cole's is the place for this and all other Beretta things. My wife shoots and loves a very nice, old 680. It does have the rounded fore arm condition based on years of use. It extracts, not ejects. She likes that. I send the gun with my 682X to Cole's for normal service. The first time Rich called me and wanted to know if I wanted to leave the 680 as extract only. He was fine with that choice, clearly understanding how it contributes to conjugal felicity. Since then I just note it in the cover letter and they leave it alone.
Ejection does not bother me, but it does bother She Who Must Be Obeyed so hers extracts only. And there is peace in the valley.
