MK9 or MK40 Mag problems?

[Rangemeister]

My son-in-law recently had a broken follower on an MK40 Elite! I told him to call the factory and they did send him another. Hope this is not a reoccurrence!

Thanks for the replies.
Hearing of broken followers in the MK40 pistols sort of shoots the hell out of my theory that the poly frame of the PM and CM pistols is partially at fault.

No problems with my MK9 mags.

I'm curious, given the fact that the MK line of pistols utilize the same magazines as the CM and PM pistols, have any owners of either the MK9 or MK40 pistols experienced magazine problems or failures such as the bodies splitting or breaking followers like the CM and PM pistols do?

I don't seem to find any posts in this forum to indicate such.

I'm wondering if the SS frame of the MK pistols which should flex way less than the polymer frame of the CM and PM pistols has any influence on how the barrel feed ramp may contact the mag followers.

My MK40 Elite five and six round stainless steel mags have been flawless.
