Magpul FMG-9

The Magpul FMG-9 is a prototype folding submachine gun, designed by Magpul Industries in 2008. It is made out of polymer in place of metal, reducing weight. The FMG-9 never left the prototype stage, and never saw widespread production on any level, as the item was only produced by Magpul as a proof of concept.

Airsoft
In 2010, Magpul Industries' PTS (Professional Training and Simulation) Division in cooperation with KWA Performance Industries released the FPG (Folding Pocket Gun). The FPG is almost identical to the FMG-9 prototype, but contains the firing mechanism of an airsoft KWA G18C replica. The FPG fires 6mm pellets with a magazine capacity of 49 rounds.

FDP-9
In 2021, Magpul unveiled the FDC-9 (Folding Defensive Carbine) and FDP-9 (Folding Defensive Pistol), two redesigned versions of the FMG-9, that are planned to release in 2023.
