The photograph I posted at the start of this thread shows my P7 with a box of 147-grain Remington Golden Saber BJHP ammunition. That is the load I have been using in my P7 without any malfunctions. However, during my "continued education" on the HK P7 (a pistol in which I have long had an interest but acquired only two years ago), it has recently come to my attention that Helmut Weldle, the engineer who designed the pistol, designed its gas-retarded action specifically around the 115/124-grain NATO round. Although I have not experienced any difficulties with 147-grain ammunition in my own P7, I've now switched to a 124-grain load for the pistol in keeping with what I understand the designer to have intended.
