Back Strap Safety

A spring loaded portion of the back of a handgun’s grip that is equipped with this device. When this firearm is at rest and not grasped for use, the BSS will be on and engaged, so the firearm will not fire even if the trigger is depressed. But, when that firearm is properly grasped for shooting the normal grip of the hand will depress the BSS into the grip which will disengage this safety and thus allow this firearm to be fired normally by the trigger
