Garry was born in Los Angeles, CA in 1944. At age 11 he was given a Civil War vintage Remington Beals Navy revolver, and this began his passion for firearms. After graduating from college with a degree in journalism, he joined the U.S. Army, eventually becoming an Ordnance ammunition officer. Posting to an ammo depot in South Wales, UK, enabled him to further study and shoot old firearms, and after discharge, he joined the staff of "Guns & Ammo" magazine in 1971. As well as acting as Arms & Armour Expert for the auction firm of Sotheby Parke Bernet, Garry has been a technical advisor for films and television, including the popular History Channel series, "Tales of the Gun," and "Mail Call."
