Personal defense weapon

Self-defense firearm

Personal defense weapons (PDWs) are a class of compact, magazine-fed automatic firearms that are typically submachine guns designed to fire rifle-like cartridges. Most PDWs fire a small-caliber, high-velocity centerfire bottleneck cartridge resembling a scaled-down intermediate cartridge, essentially making them an "in-between" hybrid between a submachine gun and a conventional carbine.
