The P7K3 Triple Duty P7 Cal. 9mm Kurz (.380)/7.65mm (.32)/.22 LR
The P7K3 is a slightly smaller version of the 9mm P7 with an interesting twist-- Caliber convertible. Available in three calibers, 9mm Kurz (German for 'short'-- 'Koorts') which is .380 in U.S. caliber measurement, 7.65 mm or .32 Auto, and finally .22 Long Rifle. With a combination of a second slide, three barrels and three magazines, the shooter has quite a versatile package in one system.
This project was conceived in 1983 with production models beginning in 1984. As with the other P7 models, the lead designer on this project was Helmut Weldle. This was a significant design change for the P7 series, because in 9mm and other caliber P7s, the barrel was not removable
Records indicate that there are 64 models in what are called Vorserie, or prototype series. They number in range from 8701-8764.
Production for non-U.S. consumption started with serial number 101, and for the U.S. started with 001.
