kahrguy, sorry if I was touchy earlier. I have a missing dog, and am in a generally bad mood as a result...
I can comfortably say I'm skilled with small pistols. I'd also say that since the PM9 I owned, and the MK9 I currently own, only had issues with certain magazines, that I don't think it's anything I am doing.
And yes, I agree that with auto-loaders it's always a good idea to function check specific ammo makes and loads. (Which is why I do not try to run HST 147 in my SP01, for instance, but it will feed pretty much anything from 115-127gr.)
