While I have actually fired less than a complete box of ammo I have had no light strikes. Everyone so far has fired the first time I pressed the trigger. I think I would just try a second strike....which is one thing I like about this action, if it didn't work and happened more than once I would reconsider my interest in carrying it. I do like the trigger, it is like a DA revolver pull and let off....and I have fired a bunch of those. I would like to see S&W bring out an M&P Compact with this double strike trigger system.
