If the picture is legit, the gun would have indeed saved his life, especially if it was holstered.

A Reddit user commented, "A direct shot to the hip would almost certainly shatter the ilium and shred the femoral artery." A gunshot to the femoral artery, one of the largest arteries in the body, could be fatal.
