Gift the gun to me; that will solve your problem for good!! :rolleyes:

Has anyone ever considered this ring to be nothing more than a resonant frequency thing?

Jeff,
Where did you pick up that GHE?

Chris, bought it from S Barnett, for use as a clays gun. 32" barrels, 8 lbs 5 oz. I think it is loose Mod, tight mod, can't recall chokes exactly. I am still getting use to it, always been more of a game gun shooter until a big tournament sporting shooter that convinced my I would struggle shooting only 20 ga or light 7/8 loads in a light 12 ga gun.

I think this issue is no different than running a wet finger around the rim of a wine glass. You do it just right and the glass sings/hums loudly. Same with a steel gun. Somehow when the hammer drops it does so just right and triggers the resonant frequency of the steel and it sings out. I wouldn't be surprised if the loosening and tightening of screws and putting some oil or grease here and there would change or eliminate it.

Wrap the top lever in adhesive tape. See if that stops the ringing.

Jeff,
The reason I asked was because Robin Hollow recently sold the gun that I was originally talking about when this post started years ago. Mine was a 30" gun in crisp next to new condition. It would have been funny if we were talking about the same gun.

All of my Parkers ring, some only one barrel. Have always found it something I liked about them. The 2 that ring both barrels each has a different tone and with ear protection and a solid wood to wood mount it can be heard when fired.
