I've personally seen Mr. Munden shoot a couple of different times. He is more than just fast. You blink and you will have missed not only the draw, but also the shot and the impact.
He does a really great show and goes into a lot of detail about fast draw and the myth of the old west gunfight. He also talks a lot about the old Hollywood cowboys and how they did at fast draw. You'd never know but two of Hollywood's fastest were Jerry Lewis and Sammy Davis Junior. Bob has Sammy's guns on display when he does his shows, (those are some beautiful guns).
