The FGC9 is a 9mm semi-automatic pistol / carbine designed to be 3D printed and combined with some metal components including steel tubing and bar stock easily ordered worldwide. It is currently being developed by Deterrence Dispensed.
The DIY barrel on the FGC9 is made from steel tube which is rifled using an extremely simple DIY take on ECM (Electrochemical Machining) using salt water and electricity combined with a 3D printed spiral insert.
The body of the bolt is printed and contains two lengths of steel bar with one bar drilled for a makeshift firing pin. The FGC9 uses a 3D printed copy of a Glock 17 magazine developed by IvanTheTroll.
Like the original Shuty AP9, the FGC9 uses an AR fire control group. This will eventually also be printable.
