This review details the Franklin Armory binary trigger for B&T GHM9/APC9 pistols. While offering simulated rapid fire, it's prone to 'hammer follow' if cycled too quickly, making it unsuitable for self-defense but a fun range accessory. The trigger functions reliably with controlled bursts and performs well suppressed.

Quick Summary

The Franklin Armory binary trigger for B&T GHM9/APC9 pistols allows one shot on pull and one on release. However, rapid cycling can cause 'hammer follow' malfunctions, making it best suited for controlled bursts as a range accessory rather than for self-defense.

Frequently Asked Questions

What is a binary trigger for a B&T GHM9?

A binary trigger, like the Franklin Armory model for the B&T GHM9/APC9, allows the firearm to fire one round when the trigger is pulled and a second round when the trigger is released, effectively doubling the rate of fire in its binary mode.

What is 'hammer follow' with a binary trigger?

Hammer follow is a malfunction where the hammer follows the bolt carrier group home without being properly caught by the sear. With binary triggers, this can occur if the trigger is cycled too fast, preventing the mechanism from resetting correctly.

Is the Franklin Armory binary trigger reliable for self-defense?

The reviewer suggests the Franklin Armory binary trigger is best suited as a fun range accessory. While reliable with controlled bursts, potential 'hammer follow' issues make it less suitable for critical self-defense situations where absolute reliability is paramount.

How does the Franklin Armory binary trigger perform suppressed?

The B&T GHM9 equipped with the Franklin Armory binary trigger performed excellently when suppressed with a Griffin Armament Revolution 9. The system maintained good accuracy and reliability even with the added backpressure from the suppressor.
