I've used five of the eight-round CobraMags from Tripp Research (http://www.trippresearch.com/) for about three years in my Springfield Trophy Match. They work flawlessly. They cost a little more ($33) than the cheapest McCormicks and Metalforms, and a little less than the most expensive from those companies. I like them a little better than the others, though not for any real solid reason. One thing I can say is that when I had a couple of questions before I bought them, Virgil Tripp himself answered them and proved to be a very pleasant gentleman to deal with. If it makes any difference to you, both Tripp Research and McCormick are in Texas (Alpine and Spicewood, respectively) while Metalform is in Connecticut.
