Okay, so im watching deadliest warrior on Spike.com. Its the green beret and the spetsnaz.. The Russian had this cool holster that allowed him to keep his 9mm Makarov without a round in the pipe. He pushes down on the gun and it racks the slide and chambers a round while the pistol is being upholstered.. anyone know anything about these little gems? where to get them, what other guns they make them for?
