First time gun buyer? What should you get?

Some friends recently moved to the Shire from a less-free place. They asked me what gun they should get. I offered to teach them basic firearms safety, pointed them toward a few ranges that offer classes from beginner to advanced, some that rent guns so they can try a variety and see what they like. They said they are mainly looking for home defense, but also one that they might be able to carry around. He is big and she is small. After compiling this information, I thought it might be useful to make it a video presentation. That way others besides my friends can benefit. Maybe there are people out there like me, who didn’t have any of this knowledge at the beginning and would have loved a video like this to give me some basic understanding.
