As others have noted it is a personal choice. If you don't place your finger on the trigger it won't fire. If you have a good fitting holster designed for the exact gun your are carrying, it will not fire.
Man that sounds great in a ideal world, but not reality. I would bet many people that say that and put in a situation of life and death, and your Adrenalin is red zoned and you truly think you are about to be killed, you will go to the trigger. Just a normal reaction. Your hand and fingers with tighten up from this immense fright.
"
For example, we know that even experienced, highly trained people tend to trigger check under stress. They don't squeeze the trigger with all their might, but they contact it. Very often this happens when drawing the gun on an unidentified subject. I can't tell you how many officers I've met who've relayed stories of people they would have shot -- sometimes unjustifiably --
if their trigger had been a few pounds lighter and needed half as much movement to discharge. The lighter and shorter the trigger, especially in the absence of an engaged safety, the greater the likelihood of an accident."
Light triggers and short resets seem to be the rage with the internet. I train with a safety and have my whole life. However, for carry I like a longer trigger pull and a stronger trigger. In fact just bought a new CCW 9mm to replace one that had a trigger advertised as "short light and crisp". For years now something inside my head kept saying. WARNING!!!
Found a great 9mm, actually shoot it better and much safer. What a new peace of mind it has brought.
If you feel that you have nerves made of steel, will not ever touch the trigger, and want a light trigger than great. However I would not advise anyone that does not have those nerves to do so.
And this internet JARGON of "The best safety is the one between your ears" is correct. And if that brain between your ears is smart enough to tell you to not use a light trigger without a safety or get a longer pull with a stronger trigger then listen to it.
You cannot take back a bullet.
PS I have never bought into this nonsense of riding a reset.
