Franklin Armory® G-S173 Binary Firing System - Glock 17 Gen3 - Gold Trigger

Franklin Armory® G-S173 Binary Firing System - Glock 17 Gen3 - Gold Trigger

The Franklin Armory G‑S173 brings the patented Binary Firing System® (BFS™) to the Glock® 17 Gen3, transforming one of the world’s most popular handguns into a faster, more versatile, and more responsive platform. Designed for shooters who want reduced split times, tighter groupings, and enhanced control, the G‑S173 allows seamless switching between Semi and Binary® modes—without ever taking your eyes off the target. With an integrated mode‑indicator back plate, tritium night sights, and high‑tactile serrations, this system elevates both performance and usability. Whether for defense, training, or recreational shooting, the G‑S173 delivers a cutting‑edge upgrade that enhances speed, precision, and situational awareness. As with all BFS™ systems, the release round can be safely cancelled by switching back to Semi while the trigger is depressed, giving shooters confidence and control in every scenario.

Selectable Semi & Binary® Modes
Choose between standard semi‑auto fire or Binary® mode, which fires on both pull and release for dramatically reduced split times.

Integrated Mode Indicator
Back‑plate indicator lets you confirm your firing mode without breaking sight picture.

Tritium Night Sights
Front and rear tritium sights provide excellent low‑light visibility and fast target acquisition.

Optics‑Ready Design
Compatible with Franklin Armory adapter plates (sold separately) for easy optic integration.

Enhanced Slide Serrations
High‑tactile front and rear serrations plus anti‑glare top serrations improve grip and handling.

Easy Installation
Designed for straightforward installation, though professional installation is recommended.

Binary® Safety Functionality
Release round can be cancelled by switching back to Semi while holding the trigger.
