The October issue of Portfolio Magazine has a detailed story about the Worcester, MA-based gun manufacturing empire of Rev. Sun Myung Moon.

Kahr Arms is more than just the manufacturer of some of the smallest and most lethal weapons on earth (including the tommy gun, made famous by Al Capone). It is run and mostly owned by a son of the Reverend Sun Myung Moon, the billionaire and self-proclaimed messiah who founded the Unification Church and controls a sprawl of businesses presumably intended to sustain and defend his followers when the world as we know it ends. The gun business, along with food companies, real estate, and other holdings, will serve to protect the fortress and keep sinners at bay, according to former members, as well as supply necessary provisions after the arrival of the new world order.

Not much is known about Moon’s 37-year-old son, Justin, or how Kahr Arms fits into the church’s teachings and the reverend’s plans for world domination. People who know Justin say he travels a lot, has a penchant for fast cars and big-caliber pistols, and spends stretches of time at various family and church mansions around the globe. He is also vigorously business-minded and has personally designed most of his company’s guns. He has grown Kahr Arms into one of America’s top privately owned handgun manufacturers, with sales of around $20 million a year and climbing at an annual rate of 30 percent.

Kahr’s success could influence the future of the church itself. With the True Father, as followers call Reverend Moon, slowing down, speculation about his heir has begun to emerge. Church watchers say the fact that Justin has built a company from the ground up makes him a front-runner in any possible succession race to lead the Moonies and run a church business empire valued in the billions of dollars.
