You guys seriously worry way too much about safeties on a hand gun. Aside from a 1911 (one of the very few handguns with a manual safety that is naturally disengaged with the thumb with out having to think about its operation) I wouldn't have a carry weapon with a manually operated safety.
KEEP YOUR FRIGGIN FINGER OFF THE TRIGGER AND YOUR GUN ISN'T GOING TO FIRE ON ITS OWN! IF YOU CAN'T DO THIS THEN YOU SHOULDN'T BE CARRYING A FIREARM AT ALL!
