I have one also. I am completely satisfied with it except for one thing, the buttstock. That is just a personal preference, I don't much care for plastic stocks so I bought a walnut 870 police buttstock on Ebay and fitted it up.
There is NOTHING wrong with the plastic stock mind you.
Overall I am very impressed. It is well built, well finished, and has become my go-to shotgun for HD. I can't see any reason whatsoever why it wouldn't serve you well as a slug gun.
