If you're looking for a multiple role shotgun to use on geese & home defense I'd highly recommend a 870. Parts, barrels, and gun protectants are cheap to keep it running & looking good.

I'd also recommend running some Hevi-Shot or Kent Tungsten Matrix #2's or 4's and you'll be stacking the geese. I've had tremendous success running high density loads 1-2 shot sizes smaller opposed to premium steel BBB and BB.
