Our follower and spring is the one NOT installed.
We were quite supprised at the quality of the spring and follower.
Myself i would not bother swaping it out right right out of the gate.
Just keep it as spare for now
so your follower is the orange plastic one and the factory follower is the red anodized one? because the red anodized one is what is in my gun as it shipped from you, i assumed it was the upgraded one. my package for the spring was also open as i received it that's why i assumed you guys may have installed yours
