No math formula, no scientific studies, just my experience with maintaining over 70 Glock 22 pistols for ten years.
I agree with this.
You know, all anybody has to do is compare a new mag to an old one to see the difference. It's as simple as that! If anyone actually performs that small,easy test, they could never say that springs don't wear out. I mean really! It is
not magic, has nothing to do with anything but the fact that there is a difference. What would cause that difference?
