Sorry folks, total newbie looking for advice and this is my first post 
I am looking to purchase a shotgun for home defense. It will also go to the range with me occasionally. I'm comfortable with my decision making on handguns and rifles... but with shotguns... I need all the help I can get. So, in my recent lurking on CalGuns.net (I've been a lurker for some time), it seems the popular choice is either the Remington 870 Express Tactical or the Mossberg 500. So I started looking at the specs and found a bunch of Mossberg 500 models. I had no idea! So, here I am thinking I've narrowed it down to 2 possibilities, it was really more like 30! Now, I know some of those could be thrown out of the mix right away... but still.
So, which of the Mossberg 500 models should I be considering? I do like the 'door busting muzzle' and certainly looking at the 18"/18.5" barrel length. Pistol grip is interesting, but not sure how that is practical or if it makes firing easier/more difficult.
Any advice? THANKS!
