FRANKLIN ARMORY
The Franklin Armory BFSIII BT-C1 binary trigger for B&T APC9 is a 3-position trigger system built to cut split times and deliver faster follow-up shots on target. Whether you're running precision drills at the range, competing in tactical matches, or training for duty, this trigger gives you the mechanical advantage of firing on both the pull and the release of the trigger—something that fundamentally changes how quickly you can put rounds downrange. The BT-C1 variant is engineered specifically for B&T platforms, including the APC9, APC45, GHM9, GHM45, and SPC9, and should also work in the Pro and K variants of these firearms, though some guns may need minor fitting.
The three firing positions keep you in control: Safe mode locks the trigger completely, Semi mode delivers one round per pull (your standard semi-auto function), and Binary mode activates the dual-fire capability. The release round isn't locked in stone either—if you're holding the trigger back and need to stop, a quick flip of the ambidextrous safety selector cancels the second shot. This gives you flexibility in dynamic situations where you might change your mind mid-trigger press. With a trigger pull weight of approximately 4.5 pounds, the BFSIII BT-C1 sits in a comfortable range for controlled fire without being hair-trigger light.
This is the kind of upgrade that competitive shooters and serious tactical operators turn to when every millisecond between rounds matters. Tighter groups, faster strings, and the ability to modulate between conservative semi and aggressive binary firing make the BFSIII a purpose-built tool for those who demand more from their trigger. Installation is straightforward for APC9 owners familiar with their platforms, though we always recommend a gunsmith check-over if you're not 100% confident in your work.
| Product Name | Franklin Armory BFSIII BT-C1 Binary Trigger |
| Brand | Franklin Armory |
| Firing Modes | 3-position (Safe, Semi, Binary) |
| Compatible Platforms | B&T APC9, APC45, GHM9, GHM45, SPC9 (including Pro and K variants) |
| Trigger Pull Weight | Approximately 4.5 pounds |
| Safety | Ambidextrous safety selector |
Yes, the BT-C1 is designed to function in the B&T APC9, APC45, GHM9, GHM45, and SPC9, as well as the Pro and K variants of these firearms. Some guns may require additional fitting, so if you're unsure about installation, have a gunsmith verify compatibility before assembly.
In Binary mode (position 3), the trigger fires one round when you press it and a second round when you release it. This effectively doubles your rate of fire compared to semi-auto and cuts the time between shots significantly, which tightens your shot groups and improves split times.
Yes—if you're holding the trigger back and decide not to fire the second round, simply move the ambidextrous safety selector out of Binary mode while still holding the trigger. This cancels the release round and gives you real-time control in fluid tactical or match situations.
The BFSIII BT-C1 has a trigger pull weight of approximately 4.5 pounds, which provides clean, controlled fire without being dangerously light for safe handling.
