I can add a little bit here. I have the same mag in .45 /1911. It will not function in either my Kimber or Ruger 1911s. I've been messing around with this mag for months with no joy. Really hard to load and I don't think it has ever run three rounds in a row without failures. I have a standard length 8rd ProMag that is pretty much the same...worthless. I have 18 mags for my 1911s from assorted manufactures (Wilson, Kimber, McCormick and gun originals) the only bad mags I have are ProMags. I have some Wilsons from the 80s that have had untold number of thousands of rounds through the years and all function flawlessly. Just my 2 cents from my experience bank. I will not buy any more ProMags....no way.
