Condition 1 was standard long before Jeff Cooper attended Boot Camp: Note that the M1911 was designed for the Army (and specifically the Cavalry.) Browning was an inventor and a businessman, not a soldier, lawman, or gunfighter. His original design did not have a safety -- and was rejected by the Army. Only when he added a grip safety and a thumb safety lock would the Army accept the pistol. In other words, the M1911 was designed to be carried cocked-and-locked (Condition 1) at the Army's insistance.
