I have 4 of the 7 round mags with the Pearce pinky finger extension. I have had two of the mags collapse on me in exactly the same manner and both on the same day. I called S&W customer service and asked if there was a problem with the springs. I was assured there was no problem but as we talked some more I got the distinct feeling there was. Anyway he insisted that he send me replacement springs for all my mags even though I was only having trouble with two of them. I received the springs yesterday and they are a distinctly different color.and finish. Having been a mechanical engineer for 45 years and having designed maybe 200 different springs I know for a fact that different surface treatments can have a vastly different effect on the stress rates of the spring material. I am going to the range soon to try out the new springs.
