Used to see similar ones decades ago in South Africa, mainly farm use at short distances, in and out of a truck, sheds, lands, etc. Used an FN para or Galil folding stock. Pistol grip generic for shotgun. Seems the same stock.
Shooting one or two shots would be fine, extended shooting changes the shoulder piece of the stock into a knife edge, extremely unpleasant, depending on the loads of course.
Very handy rifle, easy to carry and quick to shoot. Adding the pistol grip gave it that extra butt length all the LE need.
