Historical profile
Designed by engineer Mieczysław Kucher in the second half of the 1950s as part of Polish programmes to replace the PPS wz. 43 with a more compact and modern weapon.
It kept the 7.62×25 mm Tokarev chambering for logistical compatibility with Warsaw Pact ammunition, using a simple open-bolt blowback action.
Built only as a small experimental batch, it never moved past the prototype stage: Polish doctrine moved directly to the 7.62×39 mm AK family, making all SMG projects obsolete.
