I have had a PP .380 (interarms), a PPK/S interarms .380, and I now have a PP in .32. The first two had feed problems and I would not stake my life on them. The PP was made in Zella in 1935 and goes bang every stinking time. They were first made in Zella, but the allies bombed the crap out of that place in WWII ,then in Ulm. After the war arms manufacturing was banned in Germany so operations were moved to France , Manhurin and marketed by interterms in the US. Now they are owned by S&W. The early guns are the best in my book. Based on my experience with the first two I had, there would have only been one very short James Bond movie. Go Here for more info:
