the G model is a decocker only the F is a manual safety with a decocker function. you can carry the F model with the safety on and the hammer back to fire the 1st shot single action or you can carry it with the hammer down and fire the 1st shot double action. The g is only safe to carry with the hammer down and fire the 1st shot double action

Hi Mike, Type F: The safety lever is both a safe on/off, and a decocker. - Type G: The lever is simply a decocker. (The difference is that the Type G has a decocker only, while Type F has a combination decocker/safety. The guns are otherwise identical.).
