I have the Shield9 & the CM9. I used to carry the CM9 until I took a 2 day course with it at front sight. I had all kinds of type 3 malfunctions during the course. The one issue most people have with the Kahr CM/PM is the mag doesn't drop free from the factory. My other issue was drawing the gun with a proper grip fast enough get good hits before the flip target turned away was a task. I don't have that problem with a FS gun or my friends Shield which I shot briefly during the course. From my experience if I shoot slow I would get no malfunctions but if I do control pairs my CM9 falls short. Needless to say I retired the CM9.
