My all-the-time is a S&W 442. When possible, due to clothing, I add a 1911 or a K or N frame Smith.
The lower capacity and slower reloading speed of a swing open revolver I consider a minor issue. For accuracy and speed, a DA revolver can keep up very well with all but the best of the single action autos, and then it is just a hairs-breadth behind.
I believe that a DA revolver, especially one with a shrouded hammer, has an advantage at contact distance or when surrounded by clothing.
