When a hand gun is held over the head, with the hand oriented palm down, so that the gun is on its side.
This is called the flounder grip, as the sites will eventually migrate to the side of the
slide, and once again be on the
top, much like a flounder's eyes migrate to the side of the flounder's head so that the eyes are both on
top.
See any armed robbery movie footage, or
flounder photos from nature documentaries.
"The bank robber was holding the gun in a flounder
grip, surely to stike
fear in his victims with his certainty of aim."
