I have yet to see a single test performed where the trigger isn't manipulated in some fashion. Even the test where a pick is used to press the sear down from the back of the slide physically moves the trigger bar and trigger. This moved the striker safety catch, and lets the striker fall all the way.
What I am curious to know is, under which scenarios does the striker safety catch actually catch the striker, and under which scenarios the second shelf on the sear catches the striker. Every test so far defeats both of these safeties by way of moving the trigger.
