New M&P magazine followers? (9mm FS)

[pwrtool45]

I just received my latest Midway order, which included another factory magazine for my full-size M&P 9mm. It has a gray follower, as opposed to the black follower in the mags that came with the pistol. The mag bodies look the same (including the S&W rollmark on the front), but the protrusion on the top-left of the follower is more "angular" (and less "curved").

Has S&W updated the M&P mags?

Yes. My first dozen or so were of the black follower variety, but a while back they shifted to the grey followers.

I've not had a problem with either, frankly.

I purchsed my MP9 in September and the mags that it came with had the grey followers. Just FYI.
