So out of curiosity I dug my 687 12 ga out of the safe. It does it too, although not as loud or pronounced as my 686 20 ga. It’s also louder in both guns when the safety is ON. When it’s off the rattle is not quite as loud. You’ve got to shake it up and down pretty hard. Since both guns did it, I’m inclined to think it’s normal, but I will get it checked out. Looks like there is an authorized Beretta repair gunsmith about 100 miles away in a town I pass through occasionally.
