Also, I'm wondering if you've tried another magazine to see if you have the same problem. If there's something slightly off with the feed lips, the extra tension of a fully loaded magazine might exacerbate it, while a reduction in spring tension by removing a round might cause it to not be so severe. I'd try another mag if different ammo doesn't fix it. Try the Speer GDs though. I use them in all my carry guns of various calibers. Good luck.
