The M3S Folding pistol was created to vastly improve concealability, comfort, safety, and firepower. It features an auto-indexing folding frame with the trigger physically locked by the fold making the Glock factory drop safety and firing pin safety are engaged. The pistol utilizes a self-indexing magazine, flat face trigger, Glock Gen 3 43 slide, and a grip retention device which helps keep the grip snug against the frame in transport mode. The M3D pistol is also designed to be compatible with larger Glock magazines. This model has a 3.39 barrel, black finish, and comes with a 13-round magazine.
