To your POST #10: It is not recommended to carry an automatic in full battery as you described. That is with a round chambered, safety in the fire position and the hammer cocked. IMHO this is very unwise as any abrupt jarring or bump can cause the hammer to fall. It would be better to keep the hammer uncocked. If you need the weapon quickly it is a minor thing to cock it.

Actually, on a 1911, even if you were foolish enough to leave the thumb safety off, the grip safety and half-cock sere (and on newer ones like the Series II Kimbers, the trigger-actuated firing pin block as well) will prevent the sort of discharge you describe. Note: professional driver on closed course. Do not imitate!
