which is a remington 12-ga 8 shot

http://big5sportinggoods.shoplocal.c...19252&offerid=
which is a mossberg 590 12-ga 9 shot 20" barrel

http://big5sportinggoods.shoplocal.c...20449&offerid=
which is a mossberg 12-ga 6 shot with an adjustable stock 18.5" barrel

they are all around the same price give or take $100, should I go with the maximum capaicty shotgun, or go for the slightly smaller barrel? its for home security so I'm not going hunting, just taking it to the range to practice.

what kind of ammo would you guys recommend? I'm going to pickup some slugs as some just in case ammo, but I proably never plan to use it.
