I read an article a few years ago testing the Smith 1917, Colt 1917, and 1911 against modern practical drills. Of the revolvers, the Smith came out ahead used DA. WW1 doctrine though was Single Action. In SA the Colt came out ahead. This mostly came down to hammer spur design with the Smith being more difficult to manipulate. I could see the traditional SA only hammer designs taking that up a notch further on performance.
