I'm looking to purchase a few new mags for my Springfield GI. It hasn't ever been picky about what it was fed or what fed it, but I want these for IDPA and 3 gun so I'd like them to work well. I've run Springfield, McCormick, Wilson, Kimber, and several random no-name mags in it and all fed well. My buddies Wilsons were the best by far, but the others were trouble free, just not as slick loading and unloading. I see Midway has the C Products 8 round with the base pad for less than $20 so they are very appealing. Anyone used them and if so how did they work?
