Norinco NP20
The NP20 is basically a NORINCO 77-B without its fancy system purported to operate the gun single handedly (which WON'T work unless you have a Schwarzenegger-like hand; I am in contact with a ChiCom gun website master, he has handled several times a standard TYPE 77 Chinese service pistol, which is smaller than the export 77-B version, and in even such a small gun, that mechanism is very hard to operate... with your average finger, you'll only get it half-way if you use it to cock the gun, while it is very light and easy to operate if you use it to close the gun slide after it has held open after going out of ammo).
