MR-78-9TM: specifications and reviews

Many domestic traumatic models of pistols are the result of alterations of already existing combat analogs.

One of the pistols, representing a modernized weapon for self-defense, based on the IZH-78-9T and the small - sized Stechkin pistol (PSM), is MR 78 9TM. These are small arms designed at the request of the arms company Kolchuga by the masters of the Izhevsk Mechanical Plant.

In 2004, the first batch of these small arms appeared in arms stores. The upgraded pistol is a limited-fire firearm and is certified as MP-78-9TM.

How is it arranged?

The MP-78-9TM pistol works using recoil with a free shutter. The USM of this weapon is of the trigger type and is designed for double action. At the same time, the automatic cocking of the fuse is performed.

After consuming the ammunition, the casing of the bolt moves to the gate delay and remains in this position until the loaded magazine is attached to the pistol. Also, the shutter cover can be removed manually from the delay. For this purpose, on its left side there is a flag safety device, which performs the function of the lever in the MP-78-9TM USM necessary to safely remove the trigger from the platoon. In the state of the armed weapon, this fuse performs blocking of the hammers, trigger hooks and the gate casing. The MP-78-9TM pistol is equipped with a handle that contains a magazine latch.

Feature of the production of trunks

OOP MP-78-9TM has a slight difference from its counterparts. In the modernized models, the welded protrusions in the trunks have been changed. Differences have affected the size, shape and placement. Since 2008, the trunks of the MR-78-9TM are equipped with projections, which increases the muzzle energy of the weapon. In production, these protrusions are formed as a result of pushing the barrel of the guns. For the work of the masters, steel is used, from which almost the entire gun is made. Light alloys are not used.

What is inherited in the new weapon from IZH-78-9TM and PSM?

Traumatic pistol MP-78-9TM, created on the basis of a small-sized Stechkin pistol, has a low weight and compactness, which is typical for the combat analogue. It, like the PSM, is equipped with small aiming devices, narrow slots of the head and thin low flies.

For IZH-78-9TM is characterized by light weight and small size. These features have become an advantage of this model of traumatic firearms.

A trauma was created as a weapon for concealed wearing and self-defense. Therefore, for him, the lightness and compactness of IZH-78-9TM was borrowed.

Light weight is considered a disadvantage, since it is difficult to retain weapons when firing powerful bullets.

Strengths

MP-78-9TM, like the PSM, on the model of which it was created, has compactness and ease. This gun is considered to be the best example of small arms of concealed wearing. It can also be used as a reserve option for self-defense.

disadvantages

In the arms market among the various traumatic pistols, the most subtle is the MR-78-9TM. Feedback from users about this weapon shows that due to the low weight during shooting, noticeable impact is noticeable. This phenomenon, according to consumers, is considered the only drawback of this traumatic pistol, especially noticeable when using powerful cartridges. Shooting with reinforced 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 a breakdown of the return spring or rupture of the barrel. It is recommended for such a pistol to use cartridges (both for self-defense and for conducting training firings). Often, when acquiring this model of small arms, the owner is forced to independently carry out some modifications.

What is the refinement of the handle?

МР-78-9ТМ is very thin. This was the reason that, despite the availability of easily accessible controls for these weapons, the gun is inconvenient to hold in the hand during firing.

This problem is corrected with thick overlays that are mounted on the handle. The lack of independent intervention in the construction of this traumatic weapon is that after the performance of any work, the warranty card loses its validity. Every owner of such small arms should remember this. Those who like to tinker with iron and seeks to improve their gun as best as possible begin to perform any work at their own peril and risk. After replacing the original pads on the handle with thicker ones, according to users, the gun is easier to hold when shooting. At the same time, altered weapons are no longer so convenient to use for concealed wearing.

What is the work with the shock-trigger mechanism?

One of the inevitable procedures that every owner of a traumatic weapon encounters is the examination of the USM. This work can be done by removing the preservative grease from the purchased MP-78-9TM. Spares when inspecting the surface of the USM must necessarily be smooth. The existing roughness or burrs must be eliminated by grinding. Also, the mechanism of the gun should not allow the friction of the parts against each other. It is recommended that the friction points be removed and sanded using a special Goa paste for such purposes.

How to fix the problems of gun ammo?

With an effective shock-trigger mechanism, the weapon system may fail. The reason is that the cartridges are punctured when fed from a pistol shop. This problem is solved by bending the edges of the store. The grinding of the chamber and gun channel will not be superfluous either. In the canal, only easily accessible places are ground. It is undesirable to treat the teeth (hedges). Especially in the 2008 models of release. This recommendation is due to the fact that after 2008 the obstructions in the barrel channels are made by indentation. Independent gross interference with the help of a file can turn a new, but with a small flaw, a traumatic gun into a useless piece of metal.

What should be taken into account when performing the fine-tuning of the pistol?

In each batch of this traumatic firearm, there may be combat units with flaws. Characteristically, in each series of issues, deficiencies always differ. Therefore, there is no clear recommendation for their elimination. In each individual case, the owner of such a pistol must decide independently, in what place and how much to undermine or bend. The main thing when starting work on improving the internal system, it is necessary to calculate everything accurately, as any careless movement of the file can spoil the entire construction of the weapon. Anyone who aspires to make his gun original, it must be remembered that, in addition to spectacular exterior design, this product is a weapon: it must be practical and convenient to operate. It is better to start debugging when it is necessary and if it is justified.

How to choose the right ammunition?

Successfully selected cartridges for this firearms will be a guarantee of its long and successful operation. The model uses traumatic ammunition, the charges of which are equipped not quickly by burning powder. In the case of a small length of the barrel during firing, a significant reduction in muzzle energy is observed. Buying powerful ammunition, the owners of this weapon should remember that their regular use can lead to the destruction of the gun. Such cartridges are designated as "killer +". They are recommended to be used only as a self-defense, but not for conducting training firings. According to some users who use slaughter munitions, they do not affect the condition of the gun barrel.

According to other owners of such weapons, it is not worthwhile to load it with live ammunition, since such a munition is equipped with a too rigid bullet, capable of eventually destroying the barrel. 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 recoil will significantly decrease. Buying ammunition weaker than 50 J, the owner of MPP-78-9ТМ may face difficulties when reloading the pistol. When shooting slaughter cartridges, it is recommended to pay attention to the fired shells. Their appearance will be a weapon status indicator. With a normally functioning gun, the used sleeve remains intact and has no blow-ups. If there is a rupture or bulging on the surface of the sleeve, it becomes a signal to the wearer that the gun has problems with the return spring.

According to user feedback, its weakening is considered a frequent phenomenon. This problem is solved by replacing the worn out spring with a more rigid one. The main thing is that she approached the pistol system. Otherwise, there is a risk that the gun will not be recharged.

About the features of operation

The user's feedback about this limited-effect firearm is that it is especially effective to use a pistol in the summer. This is due to its small thickness and small size, due to which even an easily dressed person can covertly carry this weapon. The inner pocket of the jacket or the back pocket of the jeans are considered the most common places for wearing the MR-78-9TM.

Reviews

Users of this model believe that:

• The traumatic pistol is equipped with a very powerful spring horn. The trigger axis is located at a small distance from the shutter. This, according to consumers, makes it difficult to distort it. Although some users mistakenly believe that the difficulty in jerking the shutter is due to the presence of a powerful return spring. But, in comparison with the hammer, the return model is much softer.
• The owners of these products appreciated the reliable weapon safety system. When the gun is turned on with the fuse, the trigger is released from the platoon. At the same time, the trigger and the shutter are locked. Due to the inertial trigger, which works only after interaction with the drummer, users of firearms are protected from unforeseen shots.

Conclusion

Acquiring traumatic weapons, each person first of all pays attention to its external design. The modernized model is the most subtle and easy example of traumatism. This makes it very popular among those who decided to wear the gun covertly. For anyone who plans to use this weapon as a deterrent, the MP-78-9TM will not be the best option.

On the shelves of arms stores today are a large number of modern analogs, which have compactness and reliability.
