Dewey is great but you will wait a long time for the repair. I would recommend driving to the Northern Side X Side Classic at Hausmann's Hidden Hollow in June. Jon Hosford can take the dent out for you as you watch him do it. While there, you can shoot sporting clays or look at all the great SxS guns for sale or display.
You can send pictures to me and I'll post them for you.
