He mentioned something about different numbers on the followers but it doesn't really matter. I believe the number only identifies the black from the orange but I would have to dig in my manual. Several folks put the orange followers in their gen 4 mags.
Like I mentioned earlier the only show stopper for the magazines is the gen 1-3 will not work in a left handed mag release set up which is a Gen 4-5 feature so all mags since 2009 when the Gen 4 came out have the ambi cuts for the ambi mag release set up. So all mages now even Gen 3 new Glocks (unless it's been NIB for a decade have the new gen 4 ambi mag release cuts.
Do you remember how they got the orange followers to install in the gen 4 mags?
