I have a HK4 chambered in 7.56mm with 2 clips. im in search of the complete barrel kit with clips or the remaining 3 barrels and clips. 9mm Kurz 6.35mm & .22long.

I don't think these sold well. There was one on Gunbroker in all four calibers starting at $3500 with no bids. A number of these were police guns in .32 and were sold as surplus. Good luck, but I think the cost of assembling the parts will exceed the price of three more pistols. If you can find them.

You do not want to shoot these guns with the 9mm Kurz (.380 ACP) barrel either. The HK 4 was not originally designed to shoot the .380 and will often crack the frame with extended use of that round.
