The National Shooting Sports Foundation is the firearms industry trade organization that exists to support all areas of business related to the manufacture, sale, and use of firearms. In addition to many of the normal trade organization activities they conduct, they have taken significant steps to address the role that firearms play in suicide and suicide attempts.
They have produced several videos and a resource filled toolkit which is available to member businesses for distribution to customers. The toolkit includes many useful outreach items, such as a resource-filled pamphlet that you can download for free.
Despite the cries of anti-gun activists who are often more concerned about their political agenda than truly helping people, there are many gun owners who care deeply about issues such as irresponsibility with firearms and suicide. The NSSF is a leading example of what Firearms Responsibility Advocacy looks like and we at WTTA are proud to be affiliated with them.
