I used a browning BPS for much of my younger life.
Now, i use an 11-87lh. It was a bit spendy, but it works great, and not haveing to "fiddle" when i want to load rounds is nice. It's a bit heavy, though. (But i'm 5'10" and 130 lbs, so YMMV)
For a pump, you can't go wrong with the 870 lh (keep in mind, though, that because it's left hand, most 870 barrels won't work on it. You need to get left handed ones, although I could be wrong. )
