I have had a P-30 for about 3 years. I shoot almost exclusively my own reloads which consist of VV N320 and a 125/125 gr bullet. I have tuned these to comfortably make power factor [125,000]. They are by no means full power and exhibit low flash in low/no light conditions. I don't know how this load compares to the PMC 115's you are shooting except that both maybe lower powered ammunition. The only issue I have ever had is when I was in a compromised shooting position, right hander crossing to my right shooting across my body dragging a dummy. Failure to extract almost every shot. It was, and is, in my opinion that the combination of less than full power ammo combined with a relatively weak shooting position combined to form a less than ideal backstop for the pistol.
