Firearms Facts: Personal Defense Weapons
This video defines Personal Defense Weapons (PDWs) as compact firearms for close-quarters combat, typically under 100 yards, firing intermediate cartridges. It contrasts modern PDW calibers like 5.7x28mm and 4.6x30mm, noting the 5.7x28mm's NATO favorability for its armor penetration and reduced over-penetration. The discussion also touches on historical precursors to the PDW concept.
