Heard of this project years ago. Just recently rediscovered them. "Project ChildSafe" is a program of the National Shooting Sports Foundation promoting child and firearm safety. Lot of good thoughtful safety info on their web sight including info on how and from who to receive a free pamphlet and cable lock for firearms.
