Frame, barrel, action, trigger, grip ... understanding what these terms mean and what part of your gun they describe is critical to gun safety. When it comes to guns, there are some universal constants but there are also many variations on the basic definition of a "gun."

In this great video courtesy of our friends at NRA Women, you'll get a simple, plain-English definition of what makes up a firearm and how those parts are properly defined.
