I didn't care for the review, he uses his Glock too much for a comparison. Let's see, sight radius difference of .09 inch between the two, .07 inch height difference (so his photo is misleading), 2 ounce weight difference, heavier trigger than a Glock?? The click after pulling the trigger, IIRC, it happens about 1 mm out, but nothing wrong with the reset distance.
Is he really saying a Glock trigger is nicer than a stock M&P? Sure, it may be lighter (I doubt it), but you have to start pulling it in Montana, and walk backwards to Regina.
