There is no "manual" safety. The trigger safety prevents the gun from firing unless the trigger is purposely pulled throught the short cycle. It functions like a Glock in that regard. If one is in a possible gun grab situation, simply press the decocker, all that is necessary to return the gun to firing mode is pull the slide back 1/8" of an inch. It is an excellent system, at first the trigger may seem a little gritty, but will smooth out after a couple hundred rounds-something that anyone should do before depending on a semi auto pistol anyway.
