I ran McCormick Powermag 8 and 10's, and still do. I liked them better than the Wilsons since the 8rd Wilson floorplates came off too readily in the 8rd version of the day. The McCormick bodies felt sturdier, the floorplates stayed on, the 10 rounders don't have that front metal tab like the Wilsons, and they ran 100%. I have not tried the latest Wilson offerings, though, as I don't run 1911 much, and I have a pile of McCormicks. In reality, we were issued Wilson 7 rounders, and I trained with those some, but mostly all McCormick, all the time.
