Glock 24 Round 9mm Magazine - Why 24?

[KonstantOne]

Glock recently released a 9mm double stack magazine in 24 round capacity. I bought one to check out the size and see where/if it would be applicable.
Something interesting caught my attention. The capacity is an even number and the witness holes end a bit lopsided, unlike every other mag in this lineup (similar to the 22 round .40 mag).
Does anyone know why this would be done when every other double stack 9mm mag completes the last row with enough room for the spring and flower below, even the larger 33rnd?

Because it's based on the 22rd .40 cal mag that was made for a government customer.

Oh, why does it have the 24 hanging out there at the bottom as apposed to being paired? Probably has to do with how the mold works or that Glock doesnt care for to make it even
