I experienced issue with the rounds not being angled up thus not feeding, one thing I learned is to ensure the ammo flip flops in the magazine - I'll take picture of that little bit later unless you know what I mean.
The new follower did remedy some of the issue.
Additionally, i noticed the guy i talked to that he "filed" little bit in a angle off of the front of the magazine where the tip of the top bullet is located, preventing the tip hitting the squared off magazine.
But yeah, you can call VGW and they'll send you a red follower to try.
I'll take pictures and upload them when I get home.
