I would. I say "I would" rather than "I do" because I do not like DA/SA type trigger actions, so don't carry one now. I carried the Beretta M-9 a little bit in the military, and while I could shoot it well, I felt the switch from DA to SA after the first shot was a nuisance. We carried M-9s with round chambered, hammer down, safety off. Revolvers also work just fine with DA as the only safety. Glocks do too, and they don't have as long a DA pull as any of the DA/SA pistols I have tried. All the problems I have seen/read about with unintended discharge was because someone put his finger where it shouldn't be when he shouldn't have. Since one needs to learn how to thumb-off the safety as part of the presentation (draw), the safety doesn't do much to keep you from inadvertently pulling the trigger if you have a wandering finger.Do most people feel comfortable using the long first DA trigger pull as the only safety.
People have used single-action pistols like the 1911 and the Browning Hi Power "cocked and locked" for about a hundred years without serious difficulty. You train yourself to take the safety off as part of the presentation, so there is really no time lost. You do have to train yourself tho. When I got my first single action pistol, I specifically practiced thumbing the safety as I drew by practicing 50 presentations every night for about three weeks. That got me a good start on ingraining that movement into my draw. I have accomplished thousands of draws since then, and I can remember only two times, early on, when I fumbled switching off the safety. I now have small callous on my right thumb where it contacts the safety.The safety in a standard thumb safety which is fairly easy to thumb down, but I wondered about the time required to do that in a real situation.
I wouldn't use safety on a first-shot-double-action pistol myself, but suit yourself.
