I have had issues in 2 of my 1911s with the Shooting Star mags as well, they now sit in the safe unused.I must have gotten the lemons from Chip McCormick. I bought three of his Shooting Star mags several years ago, and they turned my will-feed-anything 1911 into a jam-o-matic. I replaced the Shooting Star followers with Wilson followers, and they run perfectly. Now all I buy are Wilson mags.
I have several of the 8 rd Kimber mags and use them more than anything else with no problems so far. But the best is the Wilson mags hands down in my 1911s.
