Heckler & Koch g11 pdw

A rather simple 3d model and renderings of the elusive hk g11 pdw a pistol that was supposed to be the side arm for the hk g11 rifle.
Similarly the hk g11 pdw would have used similar 4.73x25mm caseless cartridge just like its rifle counter part.

The gun newer saw the light of day and there is to my knowledge only one black and white picture of the gun in that has survived so the true workings of the gun are unknown.
