Flipping the safety down on a 1911 is as natural clicking a pen. And I am a Glock guy.
Agreed. It's well positioned to maximize the naturalness of the motion, thus minimizing the chance of flubbing it, even when muscle memory and fine motor coordination are adversely affected by sudden emergency. It lends itself well to intuitive operation. Minimizing isn't eliminating, though. Better, then, not to have that additional step between drawing the gun and having a functioning trigger. You can argue that safety concerns outweigh this benefit, but you can't reasonably argue that an additional step between draw and fire doesn't increase the chance of a screw up at times when fine motor coordination and muscle memory have a tendency to go out the window.
