Im really not a big fan of shotguns for anything but hunting, but I do have a few, both pump and auto, and most of them arent set up for hunting.
For hunting, I use my old SKB O/U 20 ga.
I have an old 1100 that Ive had since the 80's. I used to hunt with it some, but its been wearing a 20" rifle sighted barrel and a pistol grip stock for about 25 years now. Its always been reliable with heavy buck and slug loads.
I hunted with my dads old Auto 5 a few times as a teen. I always hated that thing, as it was long and heavy. Sucked carrying it around all day. I was more accustomed to my Ithaca Model 37, which was quite a bit lighter and handier.
The Auto 5 always seemed to work OK, but with that long barrel and the weight, it wasnt "handy" and wouldn't be my choice unless I had nothing else. I have seen a couple that were cut down just in front of the fore-end the past couple of years, and they looked like they might be a bit of a different critter.
More recently, Ive picked up a couple of the Lynx12 AK type shotguns. They are a copy of the Russian Saigas. The more I shoot them, the more I like them. They are handy like any other AK, and for the most part, handle and work just like one. They shoulder and shoot very naturally too. They have a manual BHO, and load a little differently, but its still basically the same as any AK.
I have 5 and 10 round mags for them and they are pretty handy. Its nice to just have a chestbag already loaded and not have to deal with loose rounds, bulky bags, or those typical crappy belts that always seem to be missing rounds when you go to get some. Its also nice to be able to quickly fully load the gun, or empty it if need be. And a simple mag change instantly tops off the gun. Like anything else though, you do need to put in some time with them to figure things out and get it down.
They have an adjustable gas system, and so far, with it set for the #1 buck loads I normally use in them, they have reliably fed anything Ive put in them, but the low brass Dove loads. Those worked too for the most part, but I did have a couple of stoppages when the guns were new.
If youre an AK fan, or even if you arent, they are certainly with a look. Very reasonably priced too.
