More on gun, less on ground

We have successfully managed to improve on the gun on some well needed aspects. The handle had to be screwed onto the frame in order for it not to break of should the weight of the gun rest on it. The gun now has its own power supply attached, avoiding the need for a separate heap of metal to lay on the ground and preparing for a single cable solution. Furthermore, we have attached the air spray, though only physically, not functionally.
