If your thinking clays or trap shooting you might want to consider a simi auto instead of a pump. The cost a bit more though. The upside is the recoil doesn't seem to be as bad. A nice light 20 gauge semi auto would work great for your needs. Plenty of gun for deer, clays, pheasant and bunnies.

Of course the 870 and 500 are cheaper even with both barrels. And if you get interchangable barrels get one with the scope mount on the barrel. I have a mossberg 500 as well with the tapped reciever. The only problem is if you swap barrels with this gun the scope is mounted to the reciever not the barrel. You will most likely lose your zero when swapping barrels. So get the barrel with the scope mount on it, that way the scope comes off with the barrel and will never mess your zero up.

I have had zero problems with my mossberg by the way.
