870 is a great shotgun, no doubt about it. Maybe the best, certainly one of the top three pumps.

Only problem I've seen with with them is the shell stop/action release if the trigger group is installed incorrectly {actually, quite easy to do}.

I've owned them but never liked them much merely because of the stock shape, for me. We have Ithaca 37's. This gun has a single action bar and a very reliable gun with a completely different stock shape and handling characteristics from the 870. The whole single action bar issue is so overblown. I have never seen "binding" or any other problem caused by a single action bar as described in old Remington advertisements. I have seen a problem or two with Ithacas also, just like with all mechanical things.

Ithacas have also been used by various police and military. Good guns.

But then, so are Mossbergs.
