The FN P90 in semi-automatic configuration represents the military PDW platform chambered for civilian/LE use with the original 10.4-inch barrel. While civilian sales of the short-barrel P90 are heavily regulated (NFA SBR), some states and the LE market receive semi-auto P90 variants. The P90 was developed to give rear-echelon troops a compact weapon more effective than a pistol against protected threats.
