The Jati-Matic submachine gun was designed in Finland by Jali Timari in the late 1970s and early 1980s. It is quite an unusual weapon, aimed at law enforcement forces and armored vehicle drivers. It’s production commenced in 1983 and ceased in 1987. Only about 400 of these weapons were ever produced.
The Jati-Matic is a blowback operated, selective fire submachine gun, chambered for 9 x 19 mm ammunition. The receiver is made from stamped steel. Many of the parts are made of plastic, while other are made of stainless steel and aluminum. This submachine gun has only 39 individual components.
A unique feature of this weapon is that it’s bolt recoils at inclined plane at an angle to the barrel. It gives an element of braking to the bolt and also resists the upward movement of the barrel during the fire. The pistol grip is located higher than on other SMGs. Recoil on this weapon is directed backwards, rather than upwards. It eliminates muzzle climb and makes the weapon more controllable. The Jati-Matic can be fired using only one hand.
