After being very disappointed with the ProMag 92FS 30 round magazine, I looked into getting this factory mag. I'm happy to say that it works flawlessly in my CX4 Storm carbine.
The only problem I encountered was that the spring was extremely tough the first couple times I loaded it. After leaving the mag loaded overnight, however, it loosened up and is now much easier to load. Be sure to use a magazine speed loader, though. I'm not sure if it's even possible to load this mag up by hand.
