Anyone here ever seen a Russian PSM pistol ?

[RCS]

Developed around the same time or later than the Soviet 5.45x17mm cartridge, the IMI 223 Urban cartridge is quite rare.
The 223 Urban has a 5.56mm 46 gr bullet at 1902 fps, case length is 22.95mm. Effective against most vests and design to remain inside the body and not be dangerous to others (inside aircraft too).
Weapons known are modified Mini-Uzi and Micro-Uzi machine pistols. While not as compact as the 5.45 Soviet, still an interesting cartridge
