The SAR ST10 pistol is a 9mm handgun with a traditional double-action/single-action trigger. It has a manual safety that is engaged when moved into the upper position. To fire, the shooter sweeps the safety downward. The safety can be engaged while the gun is in double action mode (hammer down) or single action mode (hammer back).  The manual safety does not act as a decocker. To take the gun out of single action and return it to double action, the shooter has to hold the hammer, pull the trigger and slowly ease the hammer down.
