Moon Kook-jin

Moon is the fourth son of Unification Church leaders Sun Myung Moon and Hak Ja Han. He was born in South Korea, and in 1973 moved to the United States, to Tarrytown, New York, with his family. He attended Hackley School, a small private school in Tarrytown. Moon, who later took the first name Justin, recounts his early interest in firearms:

My first experience shooting was with my older brother when I was 14. He also liked guns and took me shooting with friends and family. We would have a great time setting up and shooting targets with an assortment of firearms. Ever since that first shooting experience, I continued to pursue my interest in firearms.

At age 18, Moon got a license to carry a handgun, co-signed by one of his older brothers, but he wasn't satisfied with the small caliber available in a compact handgun. "I had been licensed to carry in New York State since I was 18 and had looked for an ultra-compact 9 mm. pistol," Justin later told American Handgunner magazine. "To my chagrin, I could not find a pistol with the quality of construction and features in design which I felt were appropriate for a carry gun. Therefore, I decided to design an ultra-compact 9 mm. pistol that I could carry." By his junior year of college, he decided to design one himself. "I spent the summer and much of my senior year designing the mechanical layout of the pistol and prototyping various design concepts," he told Handgunner.

Moon graduated magna cum laude from Harvard with an economics degree in 1992. In graduate school, at University of Miami, he obtained an MBA in 1993.[1]
