Does the M&P 40 use a striker like the Glock, or a partially cocked internal hammer like the HK LEM pistols. I am asking because one benefit of the partially cocked hammer is that a bad strike can be handled by simply pulling the trigger again. A bad strike on a Glock means you have to rack the slide and eject the round. I am not trying to bash Glock (or any other brand in this camp). I just think HK's LEM is an interesting evolution and I wonder if the M&P uses it. Please feel free to mention any disadvantages to the LEM that I may have overlooked. Thanks.
