One of Mussy's PDW series, the Large PDW is a chassis in which you can mount your pistol, thereby turning your handgun into a carbine-esque firearm. Your pistol is attaches to the PDW using a picatinny rail, meaning that this model will only work if your frame contains this rail.
This Large PDW is slightly longer than the related Mini PDW. It includes a collapsible brace, four rails, ambidextrous charging handles and has the ability to accept a compensator or suppressor.
Mussy notes that this design should work with Glock 17 and 18 models, 1911s, Walthers and other polymer-framed pistols.
