One of my favorite Internet resources as a gun owner is the Internet Movie Firearm Database.
I go to the movies sometimes I will see a gun I don't recognize. I enjoy following up and seeing what Make and Model it was. It's great for links and pics and discussion starters.
So if you see a big chain gun or a modified revolver for a scifi film. Check out IMFDB!
