Whether it is described as a machine pistol, a submachine gun, or a personal defense weapon, the PM63 Rak is really not the best examples of this sort of thing to actually shoot. The open-bolt/slide mechanism is very cool from an engineering and design perspective, but does in fact have a tendency to hit one in the face, as inadvertently demonstrated by my high-speed video shooting volunteer. Even if it doesn't do that, the sights reciprocating on the slide make it a difficult gun to shoot accurately.

Thanks to Movie Armament Group in Toronto for giving me the opportunity to take this to the range!
