New .45 followers... with "4" marked on them.

[ChaZ]

I just got an e-mail from my gun dealer, he said that he already ordered new parts to replace my old followers. I originally asked for "2" marked followers, but he said that the "4" marked followers are the recent upgrades and are way better than the old ones. I am wondering if any of you guys already have followers marked "4" and note any difference in its performance and looks from old followers?

Just wondering. Also thought what he told me was very informative...
