Pull trigger... BANG!
I carry single action, some without a mechanical safety switch.
I have hosted several 'active shooter' training sessions in my buildings when vacant for the cops to use Simunitions and have personally played the 'bad guy' a half dozen times... I always died.
Because of watching the cops train and seeing where they messed up and got 'shot', I stopped training on the safety latch for my EDC. What was happening time after time was upon engagement, they forgot to unsafe their weapon and got drilled every time. These were all guys that trained at the range to stay in safe, switch, fire, switch. The problem was that they reverted to idiots when under fire! Shooting 2 foot low, safety's left on, even dancing (hoping from foot to foot) when shot.
watching that go down time and time again changed my mind, draw, aim, bang!
