Instead of the old holster styles with the "strap and snap" across the backstrap or hammer area, these have the rotating hood which removes the gross motor skill of having to snap the strap across the back of the gun. In a high stress situation, it is unlikely that one would have the ability to snap that in place to secure the weapon. All you have to do with this one is rotate the hood back and it securley locks the firearm in place! Get the optional "hood" for it though, contrary to what people say it does NOT interfere with your gun draw and it is worth the extra security! Remember always practice with it before you carry it!
