Robert, IME, the DA/SA is a more modern and inherently safer design. It's as safe as a DA revolver.
As for the keyboard commandos in the gun rags asserting that one cannot "learn" to make a double tap with a DA/SA, that's untrue.
I know from personal experience, and the training of over a hundred officers, that anyone can learn that with patience and practice.
It took me about a month, and about 2K rounds of ammo, but I learned to make a rapid, accurate double tap with our new Berettas when my department transitioned.
Some of the old time writers were just too lazy to bother learning anything new or different. Cooper being the worst by far.
I agree with ATL Dave that CCW and LE have a different need.
Perhaps I am guilty of falling into the same group of "old timers" that I often criticize, but somehow after carrying a 1911 in the military, and shooting 1911s in Bullseye competition for many years, I just cannot get over the idea that I would never holster a cocked single action with a loaded chamber. Perhaps I am also too old fashioned, but the thought of carrying a 1911 in condition one makes my skin crawl like someone running their fingernails across a chalkboard.
But, DA, SAO, etc are all out there and available. So we all have the opportunity to choose for ourselves.
