Gun Runner Online Auctions has a few nice double barrel shotguns in their January auction. You can bid on these auctions now. They end on 1/14 & 1/15.
I’ve never dealt with Gunrunner, but they seem pretty legit. But be aware that all sales are final. So ask lots of questions before you bid.
A.H. Fox 12g AE – double triggers, round knob grip, nice wood. Ends 1/14
Baker 12g Paragon – double triggers, extractors, nice engraving, damascus barrels. Ends 1/15.
