The Franklin Armory BFSIII CZ-C1 Trigger, according to the manufacturer, is not yet tested with the CZ Scorpion 3+. I would recommend reaching out to Franklin Armory for more information.
I checked with Franklin Armory and the confirmed it would work with all 3 plus CZ platforms. And if you want to replace the trigger shoe with an HB trigger shoe, it would work as long as it doesn’t hit the back of the housing.
