Franklin Armory BFSIII BT-C1 Binary Curved Trigger for B&T APC9

Description

The Franklin Armory BFSIII BT-C1 is a 3-position binary firing system designed for B&T APC9, APC45, and GHM9 platforms. In the third position the trigger fires one round on pull and one round on release, producing reduced split times compared with standard semi-automatic triggers. The unit includes an ambidextrous safety selector and a curved black trigger face. Some B&T firearms may require minor interior fitting or a qualified gunsmith for proper installation; improper modification can affect serviceability and warranty.
