Tom Gresham is the host of "Gun Talk," the only nationally syndicated radio talk show about firearms, the shooting sports, and gun rights. His twentieth anniversary show is this Sunday, and he reflects on the changes that have taken place since his first broadcast. Concealed carry licenses were new, and now millions of gun owners are carrying concealed. He says that 20 years of talking about gun rights and the Second Amendment has helped to fulfill his original mission statement: to change the way people think about gun ownership. He concludes that the fight for gun rights will be eternal, that gun owners can never give an inch. Originally aired on NRA News Cam & Co 03/16/15.
