Hello this is a star wars 1313 blaster from the canceled video game star wars 1313 since it was canceled we might never find out but I was wondering if anyone knew what it might be made of. Here's a reference photo:
So seeing it is concept art and not an actual physical gun, you may need to just invent most of it. The artist looks like they took some aesthetic queues from the DL44 and a modern socom style pistol with silencer.
