All of these are on flat mags. I have two magazines with +2 extensions. One is marked .40, one is marked .357. The .357 magazine displays correct round counts up to 13 rounds (obviously, there are no holes for 14 and 15), while the .40 mag with the +2 has the same issues as the flats.
Finally, I have a pair of G31 15 round magazines that also show correct round counts. These are, obviously, marked .357.
Is there some difference between the follower in .357 magazines and the .40 ones that would cause this?
