it took kahr a bit to get the p series ( pm speceficly ) running but this is not supprising in light of the changes made to the basic kahr design ( pollimer frame , downsizing the slide ect. ) they seem to have it well in hand now . At least my pm9 is uber relyable as long as its kept clean of pocket lint and lubed . i wouldnt expect any problems with the tp tho i havnt seen or shot one myself , good thing cause momma would be " testy" when it followed me home lol
