With these magazines my Kimber custom classic does not lock back after the last round. Other magazines/followers work flawlessly. Is this a common problem with this follower?

I've been using Metalform mags for several years now and the only problem I've had is that a couple of the base plates came loose on the mags on which they were supposed to be removable. (Does that make sense?)

I've used them with a Kimber, too, although I haven't shot it much.
