I think we are already on the down hill slide in value on double guns, especially 12 gauge double guns. There are a ton of them out there for sale, some of the big dealers have inventory that has been for sale for a decade or more.
The market isn't expanding. It is graying out.
Keeping all that in perspective, just do what you want with your not-so-old gun. It isn't much of an investment.
Few guns actually are.
