I use the same buttstock for non tactical reasons, because it gives better aim and support when firing high recoil slugs, and keeps my thumb from bashing my cheek.
For mag extensions, the Tac Star one I have on an 1100 has fed perfectly but is a bit off centered. Try Choate instead. Or if you can get one, a Remington factory one, though they only go up to 7 shot, and the current model is only 6.
My personal taste would be, if you're using twin grips, to have them matching. I'd have used an ATI foregrip. But that's just me.

Anyone know why?
In general you cannot go wrong with an 870 in any variation or preference.
Thats of course assuming the shooter is practised in its use.
I have a 20 ga short stock and barrel youth version I keep in the house.
They laugh at me when I trap shoot with it untill I do as well or better than they do.
No matter what configuration yours is be sure to practise with it so you will be ready when its really needed.
The 870 is a great choice.
