I am looking to purchase a shotgun after Christmas and I know I want a tactical Mossberg 500 persuader 12 gauge. I'm just not sure which I am set on; the 6 or 8 shot. I guess it's just boiling down to looks which I know I shouldn't purchase a gun based on this. It will be used for home defense and to carry in my car occasionally. I am really looking at 2 things. Debating whether the 8 shot is necessary given the length of time a typical firefight could last vs having 2 extra shots and the customization of each gun. Does one have a greater area for customization? I know like in most cases these will boil down to personal preferences but any advice would be great. Also, does anyone know if the 6 shot breacher model can have a heat shield attached? Thanks guys and see my new member post.
