Jatimatic
This arrangement aligns the shooter's hand wrapping the pistol grip directly with the longitudinal axis of the barrel.[1] The pistol grip is also located higher than on many other submachine guns, causing recoil to be directed backwards to the user rather than upwards, eliminating muzzle climb and making the weapon more controllable when being fired one-handed.[2] The weapon's ejection port is covered in both the forward (closed) and retracted positions of the bolt assembly, protecting the gun's internal mechanisms from dust and debris.[1] However, separately sold stocks were available which fasten to the lower side of the pistol grip and give it much greater accuracy, while also protecting the rear sight from being bent or broken.[2] The submachine gun uses 20 or 40-round detachable box magazines, made of extruded aluminum with a plastic follower and a steel spring and floor plate.
