this one was made/imported 1968. It is the original 1928 version of the PP series- the PPK coming in two or three years later. It is a very shootable piece of work and has the advantage over several early to mid-20th century pistols in that, with the safety engaged it is reliably drop safe. It will produce near-fist-sized groups rapid fire from 25 yards and when fired two-handed lands a first double action shot in amongst the rest of the magazine
WHB Smith in his book of Pistols and Revovers calls the PP action " complicated but desirable."
