Assuming current production models....the grips are the only difference.
The standard 686+ ships with rubber Hogues, the deluxe with the finger groove wood grips which I believe are made by Altamont.
I'd sell the damn thing and buy a Ruger if it was mine.
You have far more patience than I do.
Are there any modern rimfire revolvers that don't have extraction issues from the factory?
That's certainly good news!
I'm not usually one to purchase online so when I saw this I had to snatch it up. Buying like that makes it hard to get a feel for the market price at times.
