i love my 870, i have a Super Express magnum... AKA it will accept 2 3/4 , 3 ,3 1/2 mag loads. so i ca go out and shoot trap then simply swap out for a slug Barrel and go hunting. its awsome and i belive it was like $240 new at wal-mart.
get the 870 or what ever shot gun you wish. then if you want to make it "bad ass" pick up a mal order catalog liek delta force or soemthign they have all sorts of doodads and furnature you can buy for your 870.
who needs it to look bad ass when you can still slam them with 000 buck shot?
as noted above if you doing any thign other than having a nightstand shotter dont go with thte short version. start with a regualr size barrel with choak tubes. the reason why i love my shotgun is that it its versitile, dont remove that and turn it in to a " hey guys look how cool this looks" gun . you REALY want to LOOK badass save you pennys and get a class 3 weapon.
