since the PM9 has polygonal rifling, would that mean a person should not shoot lead from a PM9
I would think that to be the case -- at least you would have to "de-lead" the barrel very often. You probably don't hear about this with Kahrs because they are purchased in far smaller numbers than Glock and the average Kahr is probably shot a lot less than the average Glock.
