Many domestic traumatic models of pistols are the result of alterations of existing combat analogues.
One of the pistols, representing a modernized weapon for self-defense, created on the basis of IL-78-9T and a self-loading small-sized pistol (PSM), - MP 78 9TM. This is a small arms, designed at the request of the weapons company "Mail" masters of the Izhevsk Mechanical Plant.
In 2004, the first batch of these small arms appeared in arms stores. The upgraded gun is a limited-range firearm and is certified as MP-78-9TM.
How is it arranged?
The MP-78-9TM pistol works using recoil with a free shutter. USM of this weapon is of the trigger type and is designed for double action. This automatically sets the trigger to cock the fuse.
After the ammunition is used up, the shutter guard moves to the bolt delay and remains in this position until the equipped magazine is attached to the gun. Also, the shutter housing can be manually removed from the delay. For this purpose, on its left side there is a flag fuse, which performs in the USM MR-78-9TM the function of the lever necessary for safely removing the trigger from the cock. When the weapon is on, this fuse locks the triggers, triggers and bolt guard. The MP-78-9TM gun is equipped with a handle containing a magazine latch.
Feature manufacturing trunks
OOP MP-78-9TM has a slight difference from its counterparts. In the modernized models, the welded protrusions in the trunks are changed. Differences affected size, shape and placement. Since 2008, the MP-78-9TM barrels have been equipped with protrusions, which increases the muzzle energy of the weapon. In production, these protrusions are formed as a result of punching the barrel walls of pistols. To work as craftsmen, steel is used, from which almost the entire gun is made. Light alloys are not used.
What is inherited in the new weapons from IZH-78-9TM and PSM?
The traumatic pistol MP-78-9TM, created on the basis of PSM, has a low weight and compactness, which is typical for a combat analogue. He, like PSM, is equipped with small sights, narrow slots of the rear sight and thin low flies.
IL-78-9TM is characterized by light weight and small size. These features have become an advantage of this model of traumatic firearms.
Trauma was created as a weapon for hidden wearing and self-defense. Therefore, the lightness and small-sized IZH-78-9TM were borrowed for him.
Light weight is considered a disadvantage, since it is difficult to hold weapons when firing powerful rounds.

disadvantages
Among the various traumatic pistols in the arms market, the MR-78-9TM is considered the thinnest. User reviews about this weapon indicate that due to the low weight when shooting, the recoil is noticeably noticeable. This phenomenon, according to consumers, is considered the only drawback of this traumatic gun, especially noticeable when using powerful cartridges. Shooting with heavy ammunition can significantly reduce the accuracy of weapons. Despite the fact that steel is used in production, the weapon system will not withstand the frequent use of powerful traumatic ammunition. Ignoring this feature may result in breakage of the return spring or rupture of the barrel. It is recommended to use cartridges for such a pistol (both for self-defense and for conducting training firing). Often, acquiring this model of small arms, the owner is forced to independently carry out some improvements.
What is the refinement of the handle?
MP-78-9TM is very thin. This has become the reason that, despite the presence of easily accessible controls for these weapons, the gun is inconvenient to hold in your hand while shooting.
This problem is fixed with the help of thick pads that are mounted on the handle. The disadvantage of independent intervention in the design of this traumatic weapon is that after performing any work, the warranty card loses its force. Every owner of such small arms should remember this. Those who like to mess with iron and strive to improve their gun as best as possible, begin to perform any work at their own risk. After replacing the original pads on the handles with thicker ones, according to user reviews, the gun is easier to hold when shooting. At the same time, the modified weapon is no longer so convenient to use for hidden carrying.
What is the trigger mechanism?
One of the inevitable procedures that every owner of a traumatic weapon faces is the inspection of the trigger. This work can be done by removing preservative grease from the acquired MP-78-9TM. Spare parts when examining the surface of the trigger must be smooth. Existing roughness or burrs must be removed by grinding. Also, the mechanism of the gun should not be allowed to rub parts against each other. The places of friction are recommended to be removed and sanded using special Goya paste for such purposes.
How to fix gun ammunition problems?
With a good trigger mechanism, the weapon system can fail. The reason is sticking cartridges when feeding from a pistol magazine. This problem is solved by bending the edges of the store. Also, grinding the chamber and the gun channel will not be superfluous. Only easily accessible areas are polished in the channel. To process the teeth (barriers) is undesirable. Especially in 2008 models. This recommendation is due to the fact that after 2008, barriers in the barrel channels are made by indentation. Independent gross intervention with a file can turn an acquired new, but with a slight flaw, traumatic gun into a useless piece of metal.
What you need to consider when refining the gun?
Each batch of this traumatic firearm may have combat units with flaws. Characteristically, in each episode of production, the flaws always differ. Therefore, there is no clear recommendation for their elimination. In each individual case, the owner of such a gun must decide for himself in which place and how much to grind or bend. The main thing, starting to work on improving the internal system, you need to accurately calculate everything, since any careless movement with a file can ruin the entire structure of the weapon. Those who want to make their gun original must remember that, in addition to a spectacular appearance, this product is a weapon: it must be practical and convenient to use. It is better to start the refinement when it is necessary and if it is justified.
How to choose the right ammunition?
Well-selected cartridges for this firearm traumatic weapon will guarantee its long and successful operation. The model uses traumatic ammunition, the charges of which are equipped with not quickly burning gunpowder. If there is a small barrel length during firing, a significant reduction in muzzle energy is observed. When buying powerful ammunition, the owners of these weapons should remember that their regular use can lead to a breakdown of the gun. Such cartridges are designated as “slaughter +”. They are recommended to be used only as self-defense, but not for conducting training firing. According to some users using slaughter ammunition, they do not affect the state of the gun barrel.
According to reviews of other owners of such weapons, it is generally not worth charging them with lethal ammunition, since such ammunition is equipped with a too rigid bullet that can destroy the barrel over time. For training shooting, you can buy cartridges, on the box of which there is an inscription: 50 J. If you use sports or training cartridges, the return will be significantly reduced. Buying ammunition weaker than 50 J, the owner of the MP-78-9TM LLCP may have difficulty reloading the gun. When shooting killer cartridges, it is recommended to turn your attention to the shot cartridges. Their appearance will be an indicator of the state of the weapon. With a normally functioning pistol, the used sleeve remains intact and has no swelling. If there is a gap or swelling on the surface of the sleeve, this will be a signal to the owner that the gun has problems with the return spring.
According to user reviews, its weakening is considered a frequent occurrence. This problem is solved by replacing a worn spring with a stiffer one. The main thing is that she go to the pistol system. Otherwise, there is a risk that the gun will cease to reload.
About operation features
User reviews about this limited-action firearm boil down to the fact that the use of a pistol in the summer is especially effective. This is due to its small thickness and small size, due to which even a lightly dressed person can carry this weapon hiddenly. The inside jacket pocket or the back jeans pocket are considered the most common places to wear the MP-78-9TM.
Reviews
Users of this model believe that:
- The traumatic gun is equipped with a very powerful trigger spring. The axis of the trigger is located at a small distance from the shutter. This, according to consumers, makes it difficult to distort. Although some users mistakenly believe that the difficulty in jerking the shutter is due to the presence of a powerful return spring. But, compared with the trigger, the return model is much softer.
- The owners of these products praised the reliable safety system of weapons. When you turn on the gun with a fuse, the trigger is pulled from the platoon. At the same time, the trigger and the shutter lock. Due to the inertial trigger, which works only after interacting with the drummer, users of firearm traumatic weapons are protected from unforeseen shots.
