Glock 19 Gen 4 Magazines Follower Colors

[Tigerstripe]

Just received 3 10 round Glock 19 Gen 4 magazines from different sellers. Two magazines have the black followers while one has an orange one. All 3 are defiantly Gen 4 mags and not Gen 5.I thought that orange followers only came on the Gen 5s. All 3 came in Glock packaging and work in my 19 Gen 4. Just thought that this was odd.
