The MSS pistol is a special weapon that is used by members of the armed forces or specialized intelligence units. He has certain advantages that make him popular even now.
Advantages and disadvantages of the weapons presented
Such small arms as the PSS pistol have significant advantages:
- Minimal unmasking effect (a small amount of flame and noise during the shot).
- The gun is quite light and small in size, so it can be worn in a regular holster.
- Simplicity of design.
- Low cost of developing and manufacturing this weapon.
- High efficiency and solid firepower.
- Noiselessness.
- Easy storage and care.
- The ability to install an optical sight.
The MSS pistol has one small drawback: the lack of a latch that prevents the bolt from moving during firing. However, such a flaw is not significant.
History of the presented weapons
The main reason that the PSS pistol was created was the need to use such weapons, which would not only be effective, but also minimally noticeable, as well as easy to use. The presented device appeared on the balance of special services already in the 70s of the 20th century. Naturally, the number of PSS was small. They were created on the basis of the well-known pistols of Makarov and Stechkin.
At that time, the weapons presented had excellent combat qualities. A special advantage of such a device was noiselessness. However, there were certain disadvantages: the low lethal effect of the bullet (it could protect the bulletproof vest from the defeat of the enemy), in addition, the aiming range was not very high. Naturally, over time, these flaws were eliminated, since the gun was repeatedly modified and improved.
To do this, the developers began to experiment with the length of the barrel of the weapon, to create new cartridges, where the cutoff of powder gases was carried out in the sleeve. This allowed to abandon the silencers.
In 1983, the special self-loading PSS pistol was maximally improved. To date, such weapons do not exist.
Product Specifications
This gun is very convenient for special operations. It has the following technical characteristics:
- caliber - 7.62 mm;
- firing range with a sight - 50 m;
- the number of rounds in the store - 6 pcs .;
- the weight of the device without a magazine is 0.7 kg;
- bullet speed - up to 200 m / s;
- rate of fire in combat conditions - 24 rounds per minute;
- good penetration, for example, from a distance of 20 m the PSS-2 pistol can perforate an army helmet made of steel.
For the operation of the device, special cartridges SP-4 are used, which have a length of 4.2 cm.
Design features of weapons
So, to begin with, we’ll deal with the trigger mechanism. The fact is that his device completely copies the similar mechanism of
a Makarov pistol, which has long been tested by time and has proven itself in work. It has such features: a plate-type mainspring and a half-open double-action trigger. After all the cartridges are shot, the slide delay must be removed manually. At the same time, the device is preparing for a shot.
The store device is single-row, but has a sufficiently large width. The fact is that the length of the cartridge is slightly more than the standard indicator, since the exhaust gas is cut off inside the sleeve. This ensures a silent effect.
As for the automation of the cartridge, it works due to the recoil energy of the free shutter. The silent PSS pistol has a special magazine equipped with tides that facilitate the delivery of a cartridge.
Features of the use of weapons
These silent pistols are used by the army and special forces. Due to its special properties, weapons are a great option for sabotage or liberation operations. It is used most often in cases where it is impossible to reach the enemy with a knife or if it is impossible to use other weapons. The fact is that the gun does not produce noise, fire flashes and has a low weight.
It should be noted that such weapons are not issued to standard police or army units. This type of gun does not need a silencer, and this makes its use as convenient as possible.
Features pistol PSS "Vul"
In principle, its technical characteristics are no different from the standard for this type of device. The weapon is used in armament of intelligence units and state security services. Such a gun is the most inconspicuous, light and easy to operate. At the same time, it is a very effective
military weapon capable of destroying the enemy.
The main feature of the presented device is that it has small dimensions, in particular a small barrel length. This structure was achieved through the use of special cartridges SP-4. The PSS pistol "Vul" does not require a silencer, since without it it works very quietly.
The only drawback of the presented weapon is that it is quite expensive to produce ammunition. The principle of operation of the device is quite simple: during a shot, a bullet exits the sleeve and moves along the barrel, on which there are cuts. Those gases that are inside the barrel create a certain pressure. It contributes to the separation of the sleeve and its movement back. After that she is pushed out.
Thanks to the smooth braking of the shutter, the device works silently, since the clang of metal structural elements is practically inaudible. After the bullet leaves the barrel, it is depressurized. Due to this, the pistol does not have atmospheric cotton. That's all the features of the use and structure of the weapons presented.
