I haven't in a long, long time, not since the 1st couple times I shot a 1911, but I've trained and competed with 1911s for years.
My safety is swiped off on count 2 of my draw stroke as the pistol clears the holster. As part of my "thumbs forward" grip, my shooting hand thumb rides on top of the disengaged safety. so it's become impossible to miss/forget, just due to my grip. As a matter of fact, the 1911 is the only pistol I'll carry cocked and locked. I haven't found another pistol yet that puts the safety right where I need it because of my grip.
I have seen new shooters forget to disengage (quite a few actually) when on a clock, especially those that haven't trained in a proper draw.
