1. From Chief Wallentine’s Jan. 30, 2008, e-newsletter, Xiphos.
2. As related to me by former Gunsite staff instructor (1978-1982) Emanuel Kapelsohn.
3. This number was related to me precisely and separately by former academy staffers Bert DuVernay and Tom Aveni.
4. Using a 9mm S&W M&P pistol with the standard factory trigger, muzzle at the target stand’s base for the muzzle depressed part of the drill. Target was 8.5 by 18 inches; top of target at 5 feet, 9 inches above the ground.
5. I had thought that I would be faster on the muzzle depressed part of the drill if I compressed my arms and canted my wrist, and basically extended my arms to the target to fire, compared with keeping my arms straight and raising them at full extension. I was wrong. The arms straight method was faster.
