The M9 Vertec from KJW was made entirely of metal. Using Co2 cartridges, this creates a powerful recoil and a realistic shot feeling. The handle grips are made of plastic for improved anti-slip properties and same as the metal surfaces have a dull black finish. The tactical 22 mm rail allows the attachment of laser or light dummies. The hop-up system of the M9 is adjustable and can therefore be adapted to any ball weight. The supplied 22 round Co2 magazine is filled with standard 12g Co2 cartridges. This enables the weapon to be used perfectly in winter or when the outside temperature is colder and makes it very flexible.
