Thanks for the follow up on this one.
I have forgotten the safety during a qualification run, not often but it happens. It's usually that very first shot when it happens to someone on the range BUT in a real fight that First shot is THE most important shot! I also have observed that errors increase substantially with fatigue. Boloing the safety counts as an error. I have also done quite a bit of hunting in my life. I'd like to know what hunter has never missed a shot because they were slow on the safety or forgot it altogether, I danged sure have!
Experience has taught me to appreciate a quick controlled first shot and the simple DA/DAO Pistol/Revolver does this well. The 1911 is a great gun but like you said, I am imperfect plus I get worse under high stress.
