PP-2000 submachine gun
PP-2000 submachine gun was designed by the KBP Design Bureau of Tula, Russia in 2001. The designer was Gryazev, who designed the GSh-18 pistol The Griazev was first revealed at the Sartori European Armament Exhibition in Paris, France in 2004. The appearance of the PP-2000 submachine gun is very futuristic, just like a prop from a science fiction film. Its original intention is to provide law enforcement agencies in an urban environment with a compact and lightweight automatic weapon suitable for indoor close combat. It can also be used as a second-line personnel. The individual self-defense weapon is also known as PDW. It has a caliber of 9mm and fires 9x19mm pistol rounds. It can use ordinary Parabellum rounds and can also fire Russian 7N21, 7N30, 7N31 powerful armor-piercing rounds.
Preliminary investigation of appearance
PP-2000 submachine gun has a simple and interesting appearance. Its receiver, grip and front grip are made of a whole piece of plastic. The front grip and trigger guard ring Connected as a whole to form a triangle. Due to the large distance between the front grip and the grip, the triangular trigger guard formed is also very large, and it is convenient to operate with gloves in winter. There is a section of tactical rail at the back half of the top of the receiver of PP-2000, which can be used to install photoelectric aiming devices such as red dot sights. In addition, there is also an accessory interface at the bottom of the front grip, which can be used to install tactical accessories such as tactical lights.

The bottom of the fore grip is equipped with a tactical light, the wire of the tactical light The switch is at the thumb.
Although PP-2000 uses the photoelectric sight on the rail as the main aiming device, it still retains a simple mechanical sight. There is a fixed notch camera in front of the guide rail. The camera’s corresponding meter has a range of 100m. There is a quasi-constellation with wings above the muzzle. The muzzle has a birdcage flame arrestor. If necessary, the gun Tactical accessories such as silencers can also be installed in the mouth.

PP-2000 submachine gun is equipped with 20 rounds, 30 rounds and 44 rounds of three kinds of magazines, which are inserted in the grip. Here I have to sigh the brain holes of the Russian designer after drinking vodka: The PP-2000 submachine gun in the prototype stage has 20 rounds and 44 rounds of two magazines, of which 44 rounds can be inserted in the rear of the receiver as a backup. Its non-slip patterned magazine holder base plate is stuck on the shoulder, and the entire magazine serves as a simple buttstock. However, the contact surface of such a simple butt with the shoulder is too small, which is equivalent to sticking with a stick, which is very uncomfortable. Therefore, the brain hole design of the mass production type was abandoned and honestly changed to an L shape that can be folded to the right. Metal butt stock, but the metal butt stock's installation socket still uses the original spare magazine socket, so if you prefer, you can also use the 44-round magazine as the stock.

PP-2000 submachine gun mass production type, changed to a satisfactory L-shaped metal folding bracket.

When the metal buttstock is folded, pull the hinge up, unlock it, and fold it again.
Principle of action
As a small submachine gun that fires pistols, the PP-2000 adopts a simple free gun mechanism. In order to improve shooting accuracy, it adopts a closed chamber and waits for fire. the way. The automatic mechanism of the gun is very interesting. It consists of two parts: the bolt machine and the bolt frame. There is an extended round rod in front of the bolt frame, which is located above the barrel, similar to the piston rod of a gas-guided automatic weapon., But the actual function is to pull the handle bar-there is a hinged pull handle on the head of this round rod, the pull handle can be folded to the left or right, which is convenient for left and right hand operation, and it is folded to the front when not in use. It is quite similar to the handle of the G36 rifle.
The handle of the front end of the gun frame can be folded left and right, which is convenient for changing hands.
Pull the handle, the frame of the gun frame overwhelms the hammer, and push the bullet to load, ready to launch.
When shooting, the extension rod of this gun frame will move with the automatic machine.
PP-2000 submachine gun has a safety/single burst selection lever behind the left grip of the receiver. The structure of the selector lever is also very interesting: there is a long hole on the selector lever, and the hole at the top position is aligned with a white dot on the receiver, which represents insurance; if you move down one grid, the long hole reveals the 3 on the receiver. A red dot represents a continuous shot; dial down one more grid, 2 of the 3 red dots are covered, only one red dot is exposed, and this is a single shot.

Operation insurance/single burst selection lever
Then PP- How are the single shots and bursts of the 2000 submachine gun realized? The next content is more hard-core, please watch the explanation while watching the animation, and carefully study the movement of each part:
In the single-shot state, pull the trigger, and the trigger link pulls the blocking iron. (Light blue) Rotate forward, loosen the hammer (dark blue), and turn the hammer forward to strike the firing pin (light green) at the tail of the gun to fire the bullet;
After firing, the frame and the gun are together Sit back and press the hammer backwards. When the trigger is pulled, the single-shot lever (orange-red) on the left side of the receiver rotates backwards. When the hammer is overwhelmed, it is caught by the single-shot lever. Forward rotation;
When the trigger is in place, it overwhelms the in-position safety (yellow hook-shaped part) on the right side of the receiver, but the hammer is still hooked by the single-shot lever. The shooter must release the trigger. The firing lever will turn back to a certain angle to release the hammer, but the hammer is caught by the re-lifted blocking iron, and the second round will only be fired when the trigger is pulled again.
Single shot action process, pay attention to how the orange-red single shot lever on the left side of the hammer hangs the hammer when the hammer is overwhelmed, and what happens when the trigger is released Linked with the light blue iron barrier, "pass" the hammer to the one that is caught by the iron barrier again.
In the state of continuous firing, pull the trigger, the blocking iron still rotates forward to release the hammer, and the hammer rotates to strike the needle to fire the bullet, and then it is overwhelmed by the back of the gun and the frame of the gun;
but At this time, because the insurance/single burst selector lever on the left side of the gun body is in the burst position, the single shot lever is forced to be at the rear, and cannot rotate forward when the trigger is pulled, so the hammer cannot be held. It is only held up by the right side of the in-position insurance and kept in the backward position;
When the bolt is in place, the bolt will press the front end of the in-position insurance down, and the in-position insurance will release the hammer and hit The hammer rotates forward to strike the needle, and the second shot is automatically shot;
So in the burst state, as long as the shooter pulls down the trigger, only the right side is not in place to control the hammer. When it is in place, the in-position safety is pressed down, the hammer is released, and it is automatically fired once. If the trigger is not released, the process will repeat until the bullets in the magazine are shot out.
The action process of burst shooting, pay attention to the orange-red single-shot lever on the left side does not work, and the yellow one on the right side is not in place to control the hammer. The safety in place is pressed down, and the hammer is fired automatically.
The purpose of PP-2000
Such a simple and peculiar, compact submachine gun, what kind of occasion is it suitable for? There are three general uses:
1. As a self-defense weapon for pilots, armored combat vehicle crews, artillery, pilots and other second-line combatants.use. PP-2000 is small in size (the total length is 340mm when folded, the height of 20 rounds magazine is 186mm, the width is 43mm), light weight (with a full 20 rounds magazine weighing 1.62kg), it does not increase the carrying burden too much, the shooting action is simple and even The firepower is fierce. If the 7N21, 7N30, 7N31 armor-piercing projectiles are launched, they can deal with the enemy wearing light body armor within 50m.
PP-2000 is very convenient to operate as a small submachine gun. Of course, there are disadvantages. The butt is relatively short and it is still a stick. It is very uncomfortable to stick to the cheek.
2, as a weapon carried by key security personnel. High-level officials and dignitaries need to be armed by security personnel to enter and exit high-risk places, but in some cases it is not convenient to openly carry larger weapons such as assault rifles, short assault rifles, etc. At this time, small submachine guns like PP-2000 that can be hidden in the coat can be sent. It is small in size and has stronger firepower than a pistol. Once you encounter an attack, you can use it at close range, leaving people with bullets on their faces, and covering the objects of protection quickly evacuate.
PP-2000 as a concealed weapon carried by security personnel is still good, small in size and stronger than a pistol.
3, as a CQB melee weapon for law enforcement agencies in urban environments. In anti-terrorism operations, it is often necessary to penetrate into narrow places such as houses and vehicles. It is inconvenient to carry standard-sized assault rifles, and even short assault rifles are a little too large. However, small submachine guns such as PP-2000 can be used, one if necessary. With a bulletproof shield in hand, you can shoot with a gun in the other hand.
