I handle all my weapons as if they are not drop safe, strange things can happen when a weapon falls. Then you have the case of the individual trying to control a falling weapon only to have it discharge, in this particular case the weapon discharge into the soldiers foot. Have seen a lot of weapons fall with safety on and off that did not fire. I still don't like the floating firing pin AR system, it is a sick feeling to watch a falling AR with a round in the chamber with the muzzle pointed at your head.
