as long as you pay a little attention to the military estimation, you will be familiar with China's type 92 pistol, but you don't know much about its former competitor np2000 9mm handgun. What's special about this gun? Now let's go through time and review this np2000 pistol, which finally became a foreign trade gun
as early as the early 1990s, Zhejiang Xinhua Machinery Manufacturing Co., Ltd., which has a history of more than 40 years, produced six rounds of sample guns after eight years of research and experiment, and finally passed the identification test of the national shooting range. At the end of 1999, although the gun failed to type 32, it was officially finalized as a foreign trade product due to its good performance and avant-garde shape, and was named np2000 9mm pistol.
np2000 pistol is a semi-automatic pistol with firing needle and firing, and the automatic mode is the barrel translational short recoil type. The gun adopts a unique locking ring rotary locking mechanism, which can realize single action and double action firing modes, and can replenish fire in time in case of dud. This unique mechanism design is unique among domestic pistols. The feature of this structure is that the barrel can only travel in a short distance in a straight line on the support seat during firing Therefore, the up, down, left and right swing of the barrel is extremely small
moreover, in order to reduce the impact force during opening and locking, the locking surface of the sleeve and the locking ring is designed as a spiral surface, while the guide teeth at the lower end of the locking ring and the opening and locking guide groove on the support seat are also designed as a spiral rotating surface, and the starting position of the spiral surface is accurately controlled. Therefore, the opening and locking time is very accurate and the movement is relatively stable. The disadvantage is that this kind of structure is more difficult, and the cost and manufacturing time are also increased.
np2000 pistol consists of five parts: sleeve, recoil spring and guide rod, barrel and locking ring, launcher base and magazine, with a total of 45 parts. As for the ammunition supply system of the gun, 15 rounds of high-capacity magazines with double row and double entry are used. After experiments, the ammunition supply reliability of the gun is still much higher than that of ordinary pistols of the same kind even in rainy days, wind and sand. At the same time, the gun is equipped with sleeve not in place insurance, firing needle insurance and sleeve insurance Insurance and manual insurance, which can ensure the safety of carrying and use
in terms of man-machine efficiency, this pistol is designed according to the characteristics of Asians. The whole gun is equipped with functions such as empty hanging machine, ammunition in bore indicator and firing needle ready position indicator. It highlights the humanized design, reasonable overall structure and comfortable grip. In addition, it adopts a unique locking ring rotary locking method, which makes it stable and easy to control when shooting, and the muzzle is also small and small. According to the experiment, np2000 pistol adopts a fixed target The average accuracy can reach R50=2.3cm and R100=6.7cm
