It achieves that fps because it is basically an NBB with half a blowback mech. the magazine IS the chamber for this pistol and the slide does not actually chamber a round it just blows back giving more gas to the bb's velocity and less movement to have a tighter gas trail
That answered my own question as to why it was a double action trigger
