Only used them in my colt officers 1911 and they sucked deffThey are very good in most pistols. They happen to be O.E.M. For SIG and CZ and several others. They are probably good to go in your 59. About the only pistol I haven't heard good things about Mec-Gar's mag is the 1911. And I don't know if its bad, they don't make one, or if everybody just uses Wilson or Chip McCormick, or Metalform.
Love the ones I have for my sig p226. As good as factory IMHO
They are fantastic except for 1911 magazines but it seems from what everyone on the internet says that almost all 1911 magazines are no good.
