After passing a pistol marksmanship course through the Army ROTC with a GPA of 4.0 at age eighteen, McWilliams went on to achieve world fame age twenty-seven, when he passed all shooting and written exams to receive his first concealed weapons permit from North Dakota. In 2005, he became a figure in the National Gun Debate when he publicly opposed a move by his home state’s legislature to remove the shooting portion of the CCW permit, stating that such allowed the carrying of loaded firearms by individuals who may have no knowledge of safe gun operation. Despite opposition from many sides of the issue, in 2007, he pursued other state’s carry permits, obtaining a second CCW from the state of Utah, allowing him to carry a firearm in most of the United States with reciprocity. After over a decade, he still carries a loaded firearm in public for self-defense.
In 2008, McWilliams became an avid outdoorsman, hooking sharks and tarpon, while hunting deer and elk by rifle, shotgun, and crossbow. even Savage Arms CEO, Ron Coburn, marveled at a 156-yard shot McWilliams made on an antelope from a standing vehicle. His wing shooting of ducks, doves, and pheasants also earned him a place in the history books as the first case of a totally blind hunter downing a variety of birds in flight.
On August 16, 2011, McWilliams made a different kind of history by traveling to the Florida Everglades, harvesting by 44-magnum bangstick an over 11-foot, estimated between quarter-ton and half-ton bull alligator. Standing on the mud between two gators of about equal length, he killed his gator at a frightening range of six-inches during this night hunt on shore.
