I have had my 870 express and was wanting to get a slug barrel. Instead I bought a new Mossberg 500 with three chokes, one standard vented barrel, and one Slugster barrel with rifle sights. The whole combo cost 250 so I figured it was a steal. I haven't taken it out yet. I love the 870, but is the 500 the same quality and when using the slug barrel what type slug (Brand, weight) should I get, it is a smoothbore slug barrel, and will be used mainly on coyotes and maybe deer this winter.
