MyrtleR Meany's blog : About Submachine gun Suomi-KP

Pistol – a machine gun, called Suomi, received wide acclaim during the Soviet-Finnish war. The manufacturer of this weapon in Finland itself was the company Tikkakoski Oy. It produced the product until 1944. But the army that has such weapons consisted of Finland even at the end of the 20th century, in 1990.

It supplies this sub-machine gun in other countries. For example, in Sweden, Germany, the Baltic States, some states in South America. And in Sweden, Denmark and Switzerland were established even own production of similar models under license.

At the heart of constructing the mechanism of automatic weapons is working on the principle of the free shutter. This drummer is fixed directly to the gate to be set.

It uses a unique differential lock pistol – a machine gun. Its essence is that the lock barrel is not only due to the compression force accumulated return spring, but also in this process participates moment of inertia of the moving shutter. A pinned capsule occurs before the moment when the shutter is in its front end position.

Receiver and shutter of high-quality steel. The shutter box is secured to the barrel to move like a piston, without access to air. And the cover of the back of the receiver is made with thread and is also set as airtight as possible. Mounted thereon valves provide air leakage of air out of the space formed by the shutter. A reverse airflow obstructed

As a result, during the shooting of the vacuum brake mechanism is implemented. While driving the barrel forward, a region of low pressure also slows its course. This made it possible to use the weight of the gate is small enough that a positive impact on the overall quality of shooting.

For cocking handle trunk used, which is below, and then the trunk box. In the conduct of the shooting, it remains fixed. Fuse, which is on the trigger guard on the front part of it, is also used to switch modes of fire. Although, any sandwich panels and additional elements he will flash through at any method of fire.

Another advantage of this weapon that allowed gunners to fire more effectively can quickly change the housing and barrel.

For firing this pistol – a machine gun usually uses double row stores in 20 rounds or discs to hold 70 games. But perhaps it was the use of four-shops in 50 rounds.

Due to many advantages, this model has widely used weapons in the army for a long time. She became the prototype for the future in such guns – machine guns, a Soviet PDP – 40.
