yup seen that. just imagine if it was SOB carry position. He would have blown his insides all over the place.
SOB carry is very effective when your in the know how, you carry with the grip towards the strong side, that way on the draw the muzzle sweeps away from you and doesn't sweep vitals. Simple concept, but there are clowns out there that feel the need to carry grip away and put life and limb at risk everytime they screw with it.
It isn't a good place to carry unless it's a back up piece and it is a dangerous place to carry if you are doing any type of real active movement . My unit in the military frowned upon SOB due to the fact of a slip or simple fall while wearing so much gear has caused serious lower spine damage.
