There is also the option of a rifled barrel for slugs as well. With these 2 shotguns you can't go wrong and you have a ton of options at the initial buy and later (everyone and their dog makes aftermarket parts).
Mossberg sells a model 500 package, where you can get both the 28"
hunting barrel, and the 18" HD barrel all together, with three chokes for
the hunting barrel, all for around 400$. The barrel change takes about
30 seconds, even if you're very clumsy.
I liked it so much, I bought it the first time I saw it.
