this is a PP a Super I just got that was made in 1977. It was a police surplus from the German Rhinland-Pfaltz State Police. Then imported by Interarms The gun is chambered for the 9x18 Ultra or Police round. Right now Fiocchi is the only manufacturer of this round. I shot it yesterday and its pretty snappy with that round. What looks like a safety on the slide is actually a decocker.
