Col. Sir, As long as the first one is on target, the speed with which you empty the firearm has no real relevancy. NOOOWWWW, if you should have trouble hitting on #1, best keep practicing but remember, "Take your time and fire accurately, but rapidly." I have heard it said and have seen it in action, the single action handgun is absolutely the fastest from the holster. But, you still have to make that first one count.
We have a gentleman in the Shootists that can empty a Ruger Blackhawk in less than three seconds (from the holster) and hit a 9" dinner plate sized target at 25 yds with all five rounds. I have seen him hit a 585 yd target consistently with said Blackhawk as fast as he can unload it. It is not only a phenomenal this to see but very humbling also.
Glad to hear that central Nebrasky has not turned to a cake of ice.
