Last time we compared the Speed Load to the Flying Side Kick of Karate. The comparison was that they are both very flashy, "wow" techniques, but virtually useless. The notion that "it will be there when you need it" is poorly thought out idea since we want to program success and not failure...and the speed rock will in fact lead to failure.
And so we begin - this time with the other "flying side kick"...the Speed Rock
The premise was to use it in close quarters where one was being attacked by a knife...when the standard Bill Jordan draw would be insufficient to prevent the knife man from succeeding. Nothing was ever said of the gun man's trigger finger, but in those days, it was still believed that one could beat the other man to the shot and that one's shot, hitting, would immediately kill the antagonist.
One would grip and rock the pistol out of the holster, as well rocking the upper body back so that it would coincidentally align the weapon with a higher value target on the adversary's chest. For some reason, none of those guys ever considered that the momentum of the adversary, even if shot and dying, would crash him into the shooter.
Most of those early gunmen were shooters, but very few had any sort of physical prowess, and even fewer had any sort of hand to hand skill. And in those days there was a definite separation of the two. I recall Taylor once answering a student's question with, "If you are going to fight, fight...and if you are going to shoot, shoot". Our modern understanding, based on knowing shooting as well as hand to hand, and having tested all manner of possible situations, both on the street and in simulations tells us that - sometimes you need to shoot while fighting, or fight while shooting.
But it sure looked cool back in the range only days, and yes...it was fast. I myself could speed rock a single shot in about .50 seconds...and there were those who were faster. Chuck Taylor as I recall did one in .30 once. Nonetheless, would your body even know it was dead in .50 or .30? And would that knowledge stop the plunge of the knife or the press of the trigger?
No...it would not. And as soon as we began proof testing everything via force on force, the antiquated methodologies that were so flashy on the range gave way to far more effective and sound methodologies.
First the default of movement when in a defensive mode. Next the involvement of the non shooting hand to deflect, strike and otherwise maneuver the adversary for the shot. And finally, the shoot them to the ground methodology of enhancing the ballistic damage on the adversary.
The speed rock along with the Jordan draw and the Applegate combat crouch were interesting stages in the development of close range shooting, but the methods used today exceed the effectiveness of those that were once the leading edge.
