P90

Type: Personal defense weapon. Origin: Belgium. Introduced: 1990. Action: straight blowback, closed-bolt. Common caliber(s): 5.7x28mm. Description: The FN P90 is a compact personal defense weapon designed for support troops, vehicle crews, and specialized teams. Its bullpup layout and top-mounted magazine give it high capacity in a very short package. The 5.7x28mm cartridge was intended for low recoil and improved penetration compared with pistol rounds. The P90 is easy to control and highly compact, but its specialized ammunition, unusual magazine design, and niche role make it less common than conventional carbines. Strengths generally include the role-specific advantages described above, while limitations include age, weight, recoil, cost, ammunition logistics, or reduced practicality depending on the model and configuration.
