What lendringser said is good.
You never put your finger on the trigger until you are ready to shoot - with any gun. Your finger should not be on the trigger if you have the safety on.
When I draw the 1911, the safety gets clicked off during the rotation to horizontal, but the finger is NOT on the trigger. It rides alongside the frame, just above the trigger guard/trigger. As a matter of practice, that is SOP for me. It may be that I decide to safe the gun while it is out of the holster, such as I decide not to shoot, or decide not to shoot YET, but when it first comes out during a draw, the safety comes off. If something stimulates the need to draw the gun, then I don't need the safety on at that moment, but like I said, I can always change my mind.
