I think you are being insufficiently charitable / analytical in the face of the demonstration by Wyoming Gun Project. I'm sure everyone agrees with your basic assessment that _any_ input on the trigger is a violation of one of the most fundamental rules of gun safety.
But there's nuance here.
They showed that with <=1mm of trigger pull (far less than the distance of the firing sequence), the weapon can be put into a state where miniscule input on the slide (consistent with typical holster carry) causes a discharge.
I'm not a firearms expert, but I very much doubt that any hammer-fired (and indeed, even the vast majority of striker-fired) weapons can be put into such a state.
Are you aware of any demonstration that shows another modern handgun being put into a state where this same amount of input on the slide can cause an actual discharge, let alone with <=1mm input on the trigger?
