I've fired one, for three rounds of a relatively low-recoil small shot load. Meh, but it was something I could shoot one handed with my arm fully extended and not really be bothered by it, but I don't mind some recoil that much. (I have a lot of mass, so the force needed to accelerate it is pretty impressive, and I lean into my shots.)

Personally, if you are worried about recoil, I'd look at something other than a shotgun. A pistol caliber carbine has lower recoil, more ammunition, and is more accurate at longer range. A good lever action in .357 or .44 will cost about as much, and isn't much harder to work in terms of action (is harder to reload, but you have twice as many rounds), while still giving you a nice, intimidating metal-on-metal cycling noise.
