Extreme portability in a formidable package. The FN PS90 is chambered in 5.7x28mm, and is both ergonomic and fully ambidextrous. Accuracy is maximized through the combination of blowback operation and closed-bolt firing. The barrel is MIL-SPEC, cold-hammer forged, incorporates a muzzle brake, and at 16.04" in length is civilian-legal. Models are available with 10- and 30-round polymer magazines.
