A Browning P35 Hi-Power is the quintessential SAO in 9mm. You can also find them in .40.
A CZ-75 design (avail in 9mm, .40, .45, and 10mm, not counting obsoletes) and the Taurus PT-92/99 series of firearms are DA that can always be used as a SA by being cocked and locked and never decocked.
Keep in mind that the Croatian-designed Springfield Armory XD series is also classified as SA. It looks like a Glock, but has a MUCH better trigger because the striker is fully cocked.
