Submachine Gun / Machine Pistol [ 1983 ]

The Jatimatic Submachine Gun of Finnish origin failed as a commercial product despite some promising qualities about it.

Certain groups such as police, security elements, and military vehicle crews have always appreciated a handy, concealable, and reliable submachine gun or machine pistol for general service. In the early 1980s, Jali Timari began design work on such a weapon and the resulting product became known as the "Jatimatic" (or "Jati-Matic"). The weapon proved commercially unsuccessful after it was launched in 1983 with only about 400 of the type known to be made. Disappearing in 1986, the weapon remerged as the GG-95 PDW ("Personal Defence Weapon") under the Golden Gun ltd brand label but, again, it failed to generate much market interest and was rebuffed by even the local Finnish military when evaluated.

The Jatimatic featured many tried-and-proven characteristics of a modern submachine gun: it operated from a straight blowback action, was chambered for the 9x19mm Parabellum pistol cartridge, and was of lightweight design and compact dimensions. A pistol grip was set under the rear of the receiver in the usual way with the magazine well directly ahead. The key difference of the Jatimatic versus traditional submachine gun designs was in the unique shape of the receiver which was made possible due to the upward angle taken by the bolt's recoil assembly. This allowed the pistol grip to be set higher than normal in the frame and aid in counteracting the effect of muzzle climb commonly witnessed in automatic weapons. While the rear of the receiver sported a "pinched" look, the forward section was quite normal in appearance; the barrel protruded just slightly ahead of the forend. Under the forward section of the weapon was a fold-down assembly that acted as a foregrip and this also doubled as the charging handle. The receiver was of pressed steel construction. Sighting was accomplished rather basically through an open forward sight.

The Jatimatic was fed through a 40-round detachable box magazine and magazines of the local Finnish Carl Gustav submachine gun could also be used. The trigger was given a two-mode function dictated by a "stop" where an initial pull of the trigger allowed for single-shot firing and, proceeding beyond this stop, a deeper pull of the trigger gave automatic fire.

Overall weight registered 1.65 kilograms and overall length was 14.8 inches. The barrel measured 8 inches long. Rate-of-fire equaled 600 to 650 rounds-per-minute and muzzle velocity was listed at 1,180 feet-per-second. Effective range was out to 330 feet.

Some notable tactical accessories were showcased for the gun including laser aimers, a 20-round magazine, and a suppressor.

The compact weapon failed to generate much market interest despite the benefit of inherent accuracy as the operator's trigger hand was set more in line with the barrel. However no shoulder support was part of the Jatimatic's design so full-automatic fire still held accuracy issues for such a small package. This and some notoriety helped to end the days of the Jatimatic and attempts to resurrect the line fell to naught.©MilitaryFactory.com

Straight Blowback; Semi- / Full-Automatic Fire

One shot per trigger pull; self-loading or auto-loading action aided by internal mechanism; trigger management (and initial cocking) typically required by the operator; subsequent shots are aided by the unlocked / moved bolt.
Rounds are automatically ejected from the breech, a new cartridge stripped from the feed and set in the chamber, and rounds are continuously fired so long as the trigger is pulled and an ammunition supply exists.
Blowback Operation
Gas pressure from the rearward movement of the ignited cartridge case provides the needed bolt movement, ejecting the spent case and stripping a fresh case from the magazine.
