I'm actually amazed this ammo manages to cycle your P30 at all. This gun is designed to use 9mm NATO rounds that go 1150-1300fps with 124gr bullet (power factor 142-161 - this is level of +P ammo). That is huge difference. If you want to shoot 115gr, look for something that goes around 1150fps (more/less power factor 130+) for best reliability. In my P30 and P30L, when they were "broke in" (some 2000+ rounds) I managed to shoot ammo that was on threshold of 125 power factor (115gr Blazer alu case and 124gr Barnaul steel case) and both pistols cycled, but both felt sluggish.
