BTW, on Colt Series 80 pistols, the half cock notch is not captive. You can pull the trigger from half cock, and the hammer will fall the rest of the way, but not forcefully enough to set off a round.

Correct!!
I guess we could all just put firing pin plungers on all our pistols so that it still wouldn't fire if the sear fail...but that is another idea altogether.
