I probably should have said that the lever eliminates any need to pull the trigger, although what I said/typed is true. There were a lot of highly placed police administrators who were thrilled that the M&P designs had the sear lever. [I don't know that S&W did any focus groups prior to starting design or during design. "What would you want/not want in a service pistol?"]

I don't recall any weapon prior to Gastons Gadget that had "pull the trigger" as part of the field strip directions. In any case, it was a really poor decision on the part of the design team (or teams if there were predecessors). We beat on the fact that firearms are mechanical devices and they don't care what your intent was. If there's a round present, there will be a loud noise.
