The SA design is my favorite for accuracy. A 1911 would be a good example. My S&W M&P full size in 40 or 357 Sig is just about as good without having to fuss with a hammer. My Ruger SR40C is still essentially a SA in function though the trigger arc is larger. I don't think I'd like a DA/SA gun where the first shot is different than the other shots in any sequence.
I used to think the trigger was a big deal and that accuracy was a big deal. But now I don't shoot for accuracy. It puts a lot of needless strain on you. Now I shoot for defense. I can shoot a fist-size group at 30 ft. That will kill most bad guys. The same size group will take care of a BG with a vest. You can adjust to any trigger to get this size of a group.
