Several readers sent me the link to this video, made by Tom Guilmette. It looks at a Ruger SR9c pistol in ever-increasing detail through slowing down the camera speed as the weapon is fired. It's fascinating to see how each reduction in speed reveals more of what's going on. I recommend watching it in full-screen mode.
Kudos to Mr. Guilmette for a very interesting idea. He's used the same camera to produce another slow-motion video in Las Vegas, which you'll find here along with an accompanying article.
