A recent survey of gun owners found that the most popular gun for home defense is a 12-gauge shotgun. But for some people, this is a bit too much gun to handle.

A sporting pump-action 20 gauge can be modified in various ways to not only shoot clays and deer, but also serve for home defense and as a trunk gun for people in remote areas where the nearest law enforcement agency might be miles away.
