I have owned a BPS and my 17y old son has had an 887 Nitromag and now has an 870. The 887 was a POS and after falling apart Remington replaced it under warranty. We asked they replace it with an 870 Express. The Express is decent, but nowhere near he quality of the Browning. I'm a lefty and liked the bottom eject, as will your duck blind buddies.
I later sold my BPS for a Benelli SuperNova, which I LOVE. Solid, great gun, even for a lefty. The Benelli is also a 3.5" (which is unnecessary) and shoots my 3" shells perfectly thru the 28" barrel. I prefer he Benelli to the Browning and Remingtons.
Good luck.
