This is a scarce H&K Model HK4 semi-automatic pistol set that includes the rare three additional combination conversion kit sets chambered in 22 LR, 6,35 mm and 7,65mm.

They have a one-piece duraluminum frame with a steel slide, fixed front and rear sights and hammer block safety. It is fitted with black plastic grips with a black plastic finger extension on each of the magazines. The slide has the standard H&K marking on the left side and the right side is marked "HK INC. ARL. VA.". It is complete with an original HK4 marked box that has the correct shipping label on the end identifying it as being in .380 Caliber, numbered to pistol 50030 that includes the three sets of conversion kits. The three complete conversion kits included with this pistol are original H&K manufactured and the marked barrels are chambered in 22 LR, 6,35 mm and 7,65mm.

All three sets are housed in an original H&K conversion kit shipping box with the green H&K label on the top of the lid.
