There’s a whole community of folks building semi-automatic auto-return triggers that are “technically” semi automatic, but with just a gentle squeeze, fire off another. If you maintain that grip, the return mechanism engages, returning the trigger to firing position, where your pressure causes it to fire again… it’s called a Forced Reset Trigger.
My point overall was government is fine with arbitrary exceptions that would get Stan's dad going all "Oh I'm sorry, I thought this was America."
