I have seen video of Miculek. Also once personally witnessed a Texas Ranger fire an 870 so fast that I would not have believed it had I not seen it. Even after seeing it I sometimes wonder if my memory is right.
I can’t do anything that fast. Not blink my eyes, tap my fingers or anything. It must be some kind of muscle memory.
Anyhow it is amazing.
An 870? Wonder if he had diddled the disconnector and could fire just holking the trigger back and cycling the slide? We had some ancient shotguns in the service that could do that.
