I like lightweight and midweight +P bullets in my Kahr PM9.
If you can get them to feed reliably, shoot 200 rounds of them to test, I would go with the Corbon 115 Grain +P DPX. I really like the DPX loads.
I wouldn't get too "hung up" on the "One Shot Stop" percentages if it was me. Select a good ammo and do your part by putting the bullets where they need to go. To me the most important thing is, RELIABILITY.
