Hello, VictorLouis. I believe, but am not positive, that PMP and Denel are the same ammo. PMP is loaded light. I chronographed their 115 gr ball from a BHP and got about 1120 ft/sec average velocity. It worked OK in the HP, but did not work too well with a couple of my CZ-75 pistols for the same reasons you mention. It's accurate, but light.
Best.
