It does seem to be a polarizing subject but I'm really not at either extreme. I like my CM9, I have one magazine that works fine and one magazine with a loose base plate but I'm not crazy bent out of shape over it.
My CM9 did knock out pieces of the followers but it didn't affect function of either the gun or the magazine. Another way Kahr could have fixed the problem would just be to create a cutout in the follower where the feed ramp was- eliminating the impact. Some people on KahrTalk did just that with a Dremel. I sent mine in free of charge, Kahr shortened the feed ramp a bit and I haven't had any broken followers since.
I'm happy with the little gun, I haven't had FTE, failure to feed, failure to ignite, failure to go into battery with the gun through a few hundred rounds now. And I'm surprised how easy it is to shoot accurately.
I keep meaning to call Kahr about my one mag with a loose base plate but I keep getting busy with stuff.
