We have had an 870 wingmaster in the familt for almost 30 yrs. Its USED every year and hasn't given one problem. Awsome gun. You can get a Hastings riffled barrel for it. I think you can buy it on the internet for around $180.(3 years ago)
to get a good old wingmaster, look under side of gun, if the receiver where you load you shells in is shiney, thats an older one, and if at all possible, get the magnum receiver, and i picked up a parkerized smoothbore deer bbl at gun show for 90 bucks,
that is something I learned off my dad, and i'm not knocking the new 870's, but we love the beauty of the older 870's
Cabelas has got slug barrels for that under 200. I've got an 870 wingmaster and love it for upland. Mine only shoots 2 3/4 inch shells so it not to good for turkey and waterfowl. I'm sure newer ones take larger shells. I bought a benelli nova when they first came out and love it for the turkey and ducks.

I had never shot a hog so when I poked a hole in this guy; I was determined to find him. Wearing snake leggings, I crawled on my hands and knees through the briars and the brambles and bushes where a rabbit wouldn't go. I found a spot of blood here and there but never the pig. And lucky for me, I didn't find...
