Not for defensive use

As others mention, the quality control is pretty poor on these ProMag magazines. Judging by other mags from the same brand I wouldnt trust this for more than range time. I haven't shot with them yet, but they will reliably hand cycle 5 snap caps. The magazine does not eject freely from mine, I have to pull it with quite some force. There are also some pretty ugly seam lines from the molding process (flashing). Another issue of note is the lack of a steel lining on the inside feed lips which are present on the original factory FN mags. Overall, especially for the price and lack of other options, I would say get one but don't get your hopes up.
