Gun Credibility is a free information resource intended to help creative writers, journalists, and filmmakers write about and portray firearms in a way that does not distract the audience with misused terminology, inaccuracies, impossibilities, and misinformation.
This resource is primarily built around the Glossary, which not only defines terminology, but also discusses them in a way that is accessible to the uninitiated and relevant to writers and filmmakers. Topics are heavily hyperlinked to help find the information you need.
Also planned are a series of guides for a deeper education into writing about and portraying firearms, and a list of common gotchas in each field.
