Long ago, before the town of Central Lake, Michigan decided that the money the Second Chance Shoot brought into the local economy wasn't worth having, Dick Davis had his promotional vidoes running nearly all the time at his backyard shoot. One of which was about the Second Chance Hard Corps III vest. In said video, Davis shot a guy, who was wearing the vest and standing on one foot, with an FAL from one foot away. There was no movement whatsoever by the shootee as a result of the shot. That was back in 1989. The vest was retailing at around $300US and weighed about 20 pounds. It was/is a combination of Kevlar and ceramic plates.
It has always amazed me that, after the town shut his shoot down, Dick didn't pack up his factory and move someplace that wanted the jobs. I'm guessing Dick feels that his employees' jobs are more important than a recreational shoot.
