What is this machine pistol?

[mrseven70]

This is a pix of a weapon picked up in Ramadi, Iraq by Marines in my unit. The front grip folds up and you can see the stock folds out. The armory guys think it was used in a suitcase (like an MP-5K) by bodyguards. Can anyone tell me what it is? Has small markings but no manufacture name, caliber, or anything else.

That is a polish Pz-63. 9mm caliber. It has the odd feature of the entire slide moving back and forth like an automatic pistol instead of a regular bolt assy. wildly inacurate, this gun qualifies with the ingram and sten as a bullet hose.

PM-63 or also known as wz-63. Fires 9MM Makarov. Designed as a light weapon for drivers and vehicle crews. As stated it's really a large automatic pistol.
