Condition 2 used to be real popular. Nobody used to want a cocked gun pointed at themselves safety or not. In condition 2 on an Series 70 colt the gun will only AD if dropped muzzle first, and then only on concrete. The Detonics combat masters were made with a notch on the back of slide for thumb cocking at request of a Federal Agency.
I personally know people who carried condition 2 for their entire 30+ year careers without any ADs.
