This model of a special device from the Erma-Inter company differs from other attempts to remake the legendary TT by minimal modifications and reliability. The pistol fires non-lethal ammunition in 9 mm R.A. caliber. Accordingly, the magazine with a capacity of 8 rounds is structurally similar to the magazine from the PM - this solution increased the reliability of cartridge supply and reduced the likelihood of under-firing. The barrel is steel, smooth, and tapered. The case is steel, left without significant modifications, just like the “original” fuse.
The pistol is intended for active self-defense.
