The KP series belong to a class of sub-machine guns that have proven themselves in a modern battlefield that took battles off the field and into urban and Close Quarter Battle (CQB) arenas. Popular used by Special Weapons Attack Teams (S.W.A.T.) and US Special Forces for over a decade, they're renowned for their compact sizes. Providing more firepower than hand guns without becoming as cumbersome as long arms, the KP series allowed operators to stay mobile and maneuver more effectively. Many of the KP series would evolve into Personal Defense Weapons (PDW) that provide the same versatility but offering better ranges and armor-penetrating capabilities.
