I agree RJM, if he ever has a close encounter where he has to fend off an attacker with one hand, and draw with the other, Condition 3 will have you screwing the pooch. You WILL NOT have an AD in Condition 1 unless you stick your finger in the trigger guard and pull the trigger. I have yet to see a gun fire by itself. Keep your booger hook off the bang switch, till your sights are on the target. As a matter of fact, the AD (accidental discharge) should really be changed to UD (unintentional discharge), because that's what takes place 99.9% of the time!
