better than the factory! 20/09/2014
I have been using these for the extended 45mags for a few months now and have had good results. The factory springs were designed poorly and with the taper would it would impinge on itself then bind up and become useless and it was almost impossible to get the 14th rnd in. These are more of a solid design and won't bind on themselves. I have had issue with the mags not actuating the slide catch on the last round and failing to lock back but it is still better than the factory ones binding half way through a mag. (Note: The description can be deceiving when it says high capacity. I don't think they were intended for the 14rnd 45 mags but they do work better than the factory)
Thank goodness 14/09/2013
Since S&W has, for whatever reason, chosen to leave us M&P users high and dry I had to find used mags that needed spring replacement. Thanks Brownells for this quality product. The used mags now function like the factory new mags.
