I've got an XD9 that I've had for 5 or 6 years now and I've never had any problems with the 8 magazines I've got for it. The pistol shoots great and has performed flawlessly.

If you're referring to the "rattling" issue when the mag is loaded with 13 rounds, then my XD9 mags sometimes do the same thing when fully loaded, but don't when it's at full capacity-1. Not an issue as far as functioning.
