Yes, the Safety Alert is part of the Trigger that could cause accidental discharge if weapon is dropped! I tested mine, as the video clip suggested and my trigger is functioning properly according to the Video! I see no safety alerts pertaining to external safety on S&W's website! Mine appears to be working properly as designed. Part of the problem of an external safety. is the manufacture finding the sweet spot between, stiff enough to prevent accidental engage or disengage and loose enough for flawless disengage if needed in a Crises. Weather this guy had real concerning issues about the function of the safety is debatable! What is clear to me, he never really cared for the shield and hated safety's on small Carry guns, which is puzzling to me as why he even purchased one! I dislike external safety's but Love the shield and leave mine disengaged, ignoring Smiths stupidity for putting a big wart on such a fine CC gun!!
