There were Spanish copies of the Colt SAA that had swing out cylinders, But the Colt type SAA was really an outdated design long before DA revolvers became common. It was adopted by the US Army in 1873 because it was rugged and available, and has survived primarily due to the :mystique of the "Old West". Some revolvers that look like SA's really are DA/SA, witness the Cooper percussion revolvers.
In Russia and some other European countries, the army had two versions of the military revolver, a single action version issued to NCO's and "other ranks" who were supposedly less well trained than officers, who were issued the DA version.
