I had the opportunity to handle the Polish manufactured Radom PM-06 sub machine gun at SHOT Show. This 9mm Parabellum chambered sub machine gun has a blow back action and fires at 640 rpm out of a 7.2″ barrel. It weighs 5.5 lbs. Not having fired it, my only criticism is that they only make a 15 round and 25 round magazine. 25 rounds seems a little small in 2011.
The latest model has a top picatinny rail for optics, side rails for accessories and a rail at 6 o’clock for a forgrip.
