SPRINGFIELD, Mo. • A southern Missouri sheriff and several weapons experts are examining the safety of classes required to obtain a concealed weapons permit after the accidental shooting death of a man during the class.

Glenn Seymour, 63, accidentally shot himself in the chest earlier this month in Douglas County while trying an advanced firing technique with a weapon he wasn't familiar with using.

"I think we're looking at an issue of the course of fire he was teaching," Douglas County Sheriff Chris Degase told the Springfield News-Leader. "Is it consistent with where these folks were in their training? ... In a concealed carry class, you're dealing with a lot of people who have little to no training."

The Springfield News-Leader reported that Seymour was right-handed, but was practicing drawing a semiautomatic 9 mm handgun with his left hand, taking the safety off and shooting.

Paul Richard Williams, who was teaching the class, called Seymour's death a "tragic accident."

The skill Seymour was learning when he died is not required to get a concealed weapons permit in Missouri. The state calls for instructors to cover such topics as basic marksmanship and safe storage of firearms at home during the eight-hour class.
