The Mag's Kahr makes do SUCK its the only issue we have had with the PM9 (especially) & PM45
I too hope that they design a better Mag
Just a note though:
The Kahr pistols were not designed to manually rack the slide to chamber a round (as shown in video). It says in the manual to only chamber a round using the "slide stop" lever.
Maybe its just a written solution to this particular problem though
