I have a mag that has a #2 follower. I ran across this website when trying to update my followers. GLO-1028-5 Follower fits LE magazines (full capacity) M/22,23,24,35 and 27 nine round. Use only in magazines with flat "inside guide ribs" (also marked 40&5). Replaces all followers marked "1,2,3,4 or 5". GOL-1028-1 through GLO-1028-4 have been discontinued. Part number 33 on the Glock Schematic. as opposed to this GLO-1028-8 Follower Fits LE magazines M/22,23,24,27,35. Use only in magazines supplied with 6, 7 or 8 followers. GOL-1028-6 & GLO-1028-7 have been discontinued. Part number 33 on the Glock Schematic. looks like the mag follower is specific to certain generation mags. Can someone enlighten me?
