To be more related to actuality, the safety does not come off until the the gun is well on its way to the target. But unless the safety can be opperated without any change of grip, that slows down the first shot and that could get you killed.

To me though, a thumb safety works best when re-holstering incase the edge of a holster or anything else gets caught in the trigger guard area. Not likely to happen but it sure can.

Yes, it works well for that when you remember to put it on safe. On those rare occasions, often following severe levels of stress, when you forget to put it on safe, you are likely to have no fall back habits that protect you from an accidental discharge.

There is no nice answer to this but optional safeties, as on the 1911, can lead to a false level of confidence which is not always justified. A properly designed backstrap safety would solve all these problems if combined with a slight change of technique so that the grip safety is not depressed as the pistol is re-holstered. Unfortunately, such a pistol is not made (with the half exception of the XD which I don't know well enough to make a proper comment). Why is this? Because the 1911 grip safety proved in practice to have problems to such an extent that many had it pinned off safe. The result is that manufacturers, as prone to fashion as others, stopped designing grip safeties into their pistols.

PS If you read what the man had to say, he had been practicing with a different holster which needed a thumb sweep to unlock it. Then he changed over to a Serpa which needed a trigger finger depression to unlock it. The thumb sweep took the pistol off safe and as the trigger finger did not properly unlock the Serpa he was trying to draw against unexpected resistance with his finger in the trigger guard. BANG! One moral of his experience is not to mix critical training habits. The other, for me and many others, is don't use a Serpa.
