From the guide:
If you’re like millions of Americans, you’ve either recently purchased your first gun, or you’re seriously thinking about it. Whether you have decided that you’d like to go to a range to try out a few different types of firearms to see what works best for you, or whether you want to make sure that you properly develop your skills, you will find that the guidance of a qualified mentor is a key to success. While instruction from an NRA Certified Instructor should be the foundation of firearms training, a mentor can help you build on that training. Having assistance from someone you trust will help you take charge of your personal safety in a safe, supportive environment. Your NRA is here to help you get started in what you may find to be a lifelong pursuit.
