The PP-90M1 submachine gun is the brainchild of the Tula gunsmiths, which was released in the early 90s of the XX century. The Instrument Design Bureau in Tula received this seemingly profitable order from the Ministry of Internal Affairs of Russia, which set a similar task to the designers of the Izhevsk Mechanical Plant. There was only one requirement - to create a domestic folding submachine gun by analogy with the American PP FMG (an abbreviation in English that translates as "folding submachine gun"), which was produced by the firm "Ares". Udmurt gunsmiths for some reason refused to fulfill the order, in our opinion, did not want to create a competitive model for their product - PP-19 "Bizon". For the sake of fairness, it should be noted that these products from Izhevsk masters have a high rate of fire, provide an overwhelming density of fire contact during short-term combat operations at short distances. An incomparable plus of the Izhevsk model is the large capacity of the clip. And the Tula people first released the PP-90, and soon the modernized PP-90 M (M1), which was armed not only with the Interior Ministry operatives. Such standard weapons were supplied to the corresponding units of the GUO (the former 9th Directorate of the KGB of the USSR) and the FSB of the Russian Federation. In comparison with the product "Bizon" of Izhevsk small arms masters, the "Tulak" PP-90M1 has a more original design, which involves the extensive use of plastic products, and also makes it possible to use simple, cheaper options for box-type magazines using a standard device, which at the same time is also the forend of this product.
Device submachine gun PP-90M1
The PP-90M1 submachine gun is used to deliver striking blows to the enemy at short distances and is a concealed carry weapon placed in a special pencil case-holster.
The automatic action of the product is based on the use of the return energy of the free-type bolt; when firing the shot, the barrel channel is not locked. It is brought to the position for firing from the stowed position to the firing position in 3-4 seconds due to the opening of the pencil case, in which the two leading blocks - the barrel box and the trigger, open and join into a single whole. Simultaneously with bringing these blocks to the firing position, the grip of the submachine gun with the trigger and the clip is also deployed. For the production of a shot, it remains only to rearrange the safety flag and cock the bolt. If the PP-90 fires with single cartridges, then the PP-90M1 additionally fires in automatic mode. The PP-90M1 submachine gun is so well configured and centered that the moment of overturning during firing is minimized. The mechanical rear sight and front sight are made in a folding version, the sight for preparation for firing into a combat position is set manually.

Delivery of PP-90M1 product to consumers is carried out in the following set: the product itself, two clips with a capacity of 30 rounds, a bag for carrying the product, technical documentation and wiping. Mounting on the product of devices for silent use and a flame arrester is allowed. In the stowed state, the PP-90M1 is in "operative" - the use of the variant of concealed carrying of weapons.
Using the PP-90M1 submachine gun
This product is designed for the use of Russian 9mm cartridges 7N21 and 7N31 (9x19mm PBP) of high power with armor-piercing bullets. It is also possible to use standard cartridges 9x19mm Parabellum or 9mm NATO. Thus, the 7H31 bullet "pierces" a sheet of steel 10 mm thick at a distance of 10 m. which is located above the muzzle of the barrel. This would be understandable when the product was assembled for concealed carrying of weapons and instant preparation for firing, but the lever of the safety mechanism protruding from the right side and other design features do not give rise to such conclusions.
The test results show that the scatter of the shots is in a real scatter ellipse. This means that a short burst of 4-5 rounds remains in a circle of accuracy with a diameter of 10 cm.
As a disadvantage, it is noted that the product depends on the effects of a polluted environment, which can lead to misfires and refusals to fire shots. Also, a big disadvantage is the time to bring the weapon into combat readiness.
