I don't have a 'dog in this fight' but....my #2 son, a Marine MP, said that in training down at Ft McClellan eight or ten years ago his training DI showed them what reaction time REALLy was.
The trainees were holstered (and unloaded too) with their M-9's and asked to face an instructor with a rubber knife. On command, with the trainees fully expecting an attack, the knife guy would charge them and try to get in a killing blow before he was shot. The MIMIMUM distance, with a holstered 9mm M-9 to get off a shot, was 21 feet. And that was the best of the lot. 21 feet...inside that distance, the "attacker" always got in a killing blow.
The M-9, with a round up the spout, and 12 or 13 in the mag; and double action for the first shot, could not 'stop' the attacker inside 21 feet. And...these were trained Marines, who'd been shooting literally hundreds of rounds over the period of their training. Kinda makes you think, eh Komrad.
That Alaskan guy was one he-- of a draw and shoot artist, or maybe had a slow bear, if it went down as the article said.
No disrespect for any and all in the above statements. Just wondering....
