Submachine gun chambered for 9×18 with a rifled barrel containing six left-hand grooves. The overall length with folded shoulder rest is 304 mm. It is based around and operates similar to a self-loading pistol and may have been the result of studying the mechanism of a Makarov PM.

The weapons above were used in any attack which resulted in deaths of two police officers in Odessa carried out by Valentin Doroshenko, a locally known pro-Russian activist who constructed the weapons above along with ammunition.

Pictured are locally made submachine guns seized by authorities in Nigeria. These are made to appear visually similar to the namesake rifle and include a copy of the under-folding type stock but are simple pistol caliber blow back weapons. These have recently shown up in multiple instances among arms captured from cattle rustlers and bandits.
