I just traded for a used Kahr MK9, which I am very pleased to add to my collection. It is my only Kahr. It came with 3 magazines, one of which I am curious about. It has a nice little finger extension, but the slide does not lock back when this magazine is empty. I have not had a chance to shoot the pistol yet, but simply testing it by cycling the slide by hand, it seems to feed rounds with no problem. The other 2 mags have a small metal nipple on the follower (that is not present on the magazine in question) and both of these mags lock the slide back when empty, as expected.

Can anyone enlighten me on this mystery?

Thanks,
Gonzo

I think that may be either an aftermarket mag or an old one. I think that Kahr redesigned the followers a long time ago to the little metal nub to fix a slide not locking back problem. I believe you could probably order a new follower from Kahr to resolve the issue.
