I know many shooters will
at this, but I like to carry a SAO 1911 with the hammer lowered to half-cock on a loaded chamber. At half-cock, the pistol cannot fire - period. You can pull the trigger all day long and the hammer won't fall. You can drop the pistol on its hammer and it will not fire. After a little practice, I can draw and cock the hammer with my thumb in one smooth motion.
