While being able to draw from concealment and fire quickly is important, you will likely have a lot more trouble with getting to the point of making that decision than you will with the mechanics of the draw. Unless you are really on top of your game and manage to see a bad situation unfolding in front of you and have already made decisions as to what you would do and are physically getting ready to implement those decisions, then most of your reaction time will be in the data gathering, interpretation, and decision stages. If you get a chance to see security video segments of robberies in progress, you will see that many folks have anywhere from a 3-5 delay in effecting a response to aggressive threats, assuming they ever get through the process mentally. Probably the part that hinders things the most is the interpretation of what is going on where folks stand gape-mouthed in disbelief, seemingly not believing that the SHTF right in front of them.
mete, I think you have confused the difference between properly trained and competition highly skilled. You know, there is that 'properly trained' shotgunner on American Shooter that can hold his shotgun in his left hand and toss 9 clay birds in the air with his right hand, shoulder the shotgun, and shoot all 9 individually before they hit the ground. No, he is more than just properly trained.
Two shots in under one second. Let's see. First you have approximately 0.20 seconds of reaction time to the stimulus, such as the tone of the timer. Of course, you already know you are going to draw your gun and fire it, so you don't have any decisions to make beyond when you decide to act. Plus, you are already standing in whatever optimal position you want to do the drill, something you won't likely have in reality. If you are skilled, the double tap shots will show being 0.20 seconds apart, about 0.15 if you are really good. We will assume the latter. So out of the one second, you have lost 0.35 seconds to synaptic processes. So left is 0.65 seconds to sweep open the concealment garment, grab the gun, lift, rotate to horizontal, and then start shooting. So how come people like you don't seem to come to my range? I never get to see the super fast people.
