I have been shooting my Taurus PT1911 AR for over a year now, using the factory mags, at the range with no problems....roughly 2000 rounds. When I get home a Wilson 47D stuffed with 230gr. Federal Hydrashok's replaces the factory mags, and two othe 47D's are kept loaded to back the first one up if need be. I have had these three magazines at the range every time I go and all three get shot as well. I only have 140 rounds through the three of them since the Hydrashoks are so expensive to shoot. I tried my sons Para GI mags and my other son's Kimber mags in the Taurus and have yet to find anything that will not work well in it.
Over the years I have diagnosed many FTF problems of friends 1911's as cheap mag problems by simply letting them use one of the Wilsons. Im sure there are others (Tripp, Shooting star, Brown, etc.) that are good mags as well...I have just always used what works for me and the WIlson 47D's have shot perfectly no matter what I load them into.
