Would be nice if...
I have previous experience with Lyman magazine extenders and found them usable but wanting. Unfortunately compared to their competitors they have too smooth a texture and their other models tend to pinch. I purchased one of these to see if it worked on an M&P 2.0, not really expecting it to, however, the competitor's brand is extremely hard to find...so this was worth a shot. Well, long story shorter, don't expect this to fit a M&P 2.0, it doesn't.
