Description
The Jatimatic (Jali Timari Automatic) is a 9×19mm Parabellum submachine gun from Finland. Developed in the late 1970s and early 1980s by Jali Timari, it debuted in 1983. Production was limited to approximately 400 units, initially by Tampereen Asepaja Oy, and later by Oy Golden Gun Ltd as the GG-95 PDW in 1995. The manufacturing license of Tampereen Asepaja was revoked in 1984 after a batch of 22 pieces was stolen, which ended its production.
The Jatimatic is an automatic, open bolt, blowback-operated firearm chambered for the 9×19mm Parabellum cartridge. A notable design aspect is the angle of the bolt guide rails, inclined at 7° to the bore axis. The telescopic bolt covers most of the barrel length and recoils upwards on this inclined plane. This arrangement imparts a braking element to the bolt and helps counter barrel rise during automatic fire, allowing recoil to be directed largely backwards to the shooter. The pistol grip is positioned high, aligning the shooter's hand with the barrel's longitudinal axis. The trigger housing houses a fixed ejector, while the casing extractor is in the bolt. Lacking a feed ramp due to the bolt's upward trajectory, rounds are chambered directly from the magazine by the bolt. The ejection port remains covered in both the forward and rear bolt positions. A progressive two-stage trigger offers semi-automatic fire with a momentary squeeze and fully automatic fire when pulled fully. It utilizes a striker firing mechanism with a fixed firing pin.
Construction incorporates plastic for parts, such as:
- the frame
- pistol grip/charging handle
- trigger
- sear
- disconnector
Many other components are stainless steel. The receiver is stamped sheet steel with a hinged cover. Comprising 39 components, the design lacks an integrated stock but can be fitted with an optional stock attaching to the pistol grip. Reloading involves deploying the folding vertical forward grip, which also functions as the cocking handle. The grip must be pulled rearward and then guided forward to chamber a round. When folded, the grip acts as a safety, immobilizing the bolt via a lug engaging a notch. The weapon is equipped with fixed open iron sights sighted for 100 m.
Two other versions exist. The GG-95 PDW, a re-introduction attempt in 1995 by Oy Golden Gun Ltd. The Norinco Model 411, a clone manufactured and exported by Norinco from China, is mostly identical to the original but with simplified iron sights and produced in both 9×19mm Parabellum and 7.62×25mm Tokarev calibers.
Designed primarily for police, security forces, and armored vehicle crews, the Jatimatic was never officially adopted by the Finnish Defence Forces. However, the later GG-95 PDW version underwent testing by the FDF in the 1990s. The theft of a batch from the manufacturer in 1984 led to a criminal association.
The Jatimatic was conceived for easy concealment, targeting user groups such as police and security personnel, and armored vehicle crews requiring a compact firearm. The GG-95 PDW variant was tested by the Finnish Defence Forces. The weapon is known for appearances in media such as the films Red Dawn (1984) and Cobra (1986), and as the weapon of the fictional character Wild Dog.
