Description

The Franklin Armory BFSIII BT-C1 brings the Binary Firing System GEN 3 to your B&T pistol caliber platform. This is a three-position trigger, and the magic happens in position three: you get one round on the pull and a second round as you let the trigger back out. That release shot is what tightens up your split times and lets you put two rounds close together with a single cycle of your finger. Position one is safe, position two is standard semi firing one round per pull, so you always have a familiar mode to fall back on.

What the BT-C1 Adds to Your APC9

The trigger runs an ambidextrous safety selector, so lefties and righties both get easy access without fumbling. Pull weight sits right around 4.5 pounds, giving you a clean, tactile break in both semi and binary modes. One of the smarter touches here is the ability to cancel that release shot by moving the selector out of binary mode while you hold the trigger back. That gives you a way to think twice mid-cycle instead of being locked into the second round.

Fit and Function of the BFSIII BT-C1

This one is built for the B&T APC9, APC45, GHM9, GHM45, and SPC9, and it should also run in the Pro and K variants of those guns. A few B&T lowers may need a little light fitting to the interior plastic to seat the trigger properly, and that tweak stays reverse compatible with the OEM trigger if you ever want to swap back.

Worth knowing before you head to the range: binary triggers reward a smooth, deliberate technique. If you try to slam it too fast, you can outrun the action before it resets for the release shot. Start slow, let the trigger travel fully forward, and you will feel the rhythm quickly. It is a genuinely fun and capable upgrade for competition, training, and range days.

Frequently Asked Questions

How does the BFSIII BT-C1 binary mode work?

In position three, the trigger fires one round when you pull it and a second round when you release it. That release shot is what dramatically reduces your split times between rounds. You can always flip back to position two for standard semi-auto, one round per pull.

Will the BT-C1 fit my B&T APC9?

Yes, it is designed to function in the B&T APC9, APC45, GHM9, GHM45, and SPC9, and it should also work in the Pro and K variants of those firearms. Some B&T lowers may need a bit of light fitting to the interior plastic for a proper seat. That modification stays reverse compatible with the factory OEM trigger.

Can I cancel the second shot in binary mode?

You can. If you decide not to fire the release round, just move the selector out of binary mode while holding the trigger back and the second shot is canceled. It is a handy feature that keeps you in control of every round.

Any tips for getting the most out of the BFSIII BT-C1?

Start slow and let the trigger travel fully forward between cycles. If you rush and don't let it reset completely, you can outrun the action before it is ready for the release shot. Once you find the rhythm, the paired shots come naturally and it is a blast at the range.
