I did a little more poking around on the web and found this on BudsGunShop.com: Browning HD Shotgun
Although this is the gun I was looking at, I still can't find it on Browning's site. It certainly looked like a new gun, still had a Browning sticker on the magazine. The guy at the show was asking $425, so his price wasn't great.
May be an interesting alternative to the 870 if you can get it for a fair price.
