Good grief! Bruce Gray would have a stroke!
Back int he early 1980s, when Bruce was the entire H-K R&D department, he was always cooking up P-7s in "Major 9," ie, 9mm jacked up to make the IPSC major caliber power factor. I'd see him and he'd say, "Wanna shot it?" My response was that I had grown accustomed to my hands, and having blow up two guns myself (a 1911 .38 Super and a High-Power in Major 9), I'd gotten spooky. He always looked so hurt, and pointed out to me that P-7s, as a rule, didn't blow up...unlike the French MAB he'd launched into low earth orbit.
Good lord, we were stupid back then!
