SRU posted initial computer drawings on a product that will be a built for a new airsoft GBB pistol as well. This is a bullpup conversion kit for the P320 pistol that allows for a spare magazine ready to be loaded in the grip. If you wonder which P320 pistol in airsoft is available, you can check the SIG Air Pro Force M17 GBB Pistol made by VFC or the unlicensed F17 GBB pistol from Asia Electric Gun (based on the WE design).
