Here's a quick YouTube video of the Zoraki M906 P.A.K. Blank pistol firing off some blank rounds. I fire off 6 semi-auto rounds which by the way is the magazines maximum capacity! I also capture the test fire using my Canon High Speed Slow Motion camera in 210 frames per second mode to really slow down the action and see how this small blank shooter cycles rounds.
