...between trigger and sear without rollers or balls.

wouldnt be surprised if these designs perhaps even with roller bearing would be incorperated into gun....But then again , triggers are already phenomenal.

It would take actual zero friction - which no real bearing can achieve - to do it.

built many a catapult and treboche as a kid. Built only one crossbow for my son but the trigger was perplexing at the time.

And exactly the same is true in trigger mech's. Therefore, in each case, one needs to ask, is it worth the trouble? In a cogbox, it definitely is. But in a trigger?

My guess is: No.

PS: Besides, even perfect rolling friction is still friction and not perfectly without energy loss.
