Franklin Armory G-S173 Binary Trigger & Slide Kit for Glock 17 Gen 3

Franklin Armory G-S173 Binary Trigger & Slide Kit

Franklin Armory brings their patented Binary Firing System to the Glock 17 Gen 3 platform with the G-S173 complete trigger and slide assembly. This innovative system allows shooters to select between traditional semiautomatic and binary firing modes, delivering reduced split times and tighter groupings for competitive, defensive, and recreational shooting.

How It Works

The binary trigger fires one round on the trigger pull and a second round on the trigger release, effectively doubling your rate of fire within the legal framework of semiautomatic operation. If you need to cancel the release round, simply switch back to semiautomatic mode while the trigger is depressed—a safety feature that gives you complete control.

Key Features

• Selectable firing modes: Switch between semi and binary operation without removing your hands from the gun
• Integrated mode indicator: Know your firing mode at a glance without breaking sight picture
• Tritium night sights: Front and rear tritium sights for low-light shooting
• Enhanced ergonomics: High-tactile front and rear serrations plus anti-glare top stripe serrations for positive grip and control
• Optics ready: Compatible with optics mounting systems (custom adapter plates sold separately)
• Easy installation: Drop-in design for straightforward setup

The Advantage

Whether you're training for competition, preparing for personal defense, or simply enjoying recreational shooting, the G-S173 gives you a tactical advantage through faster follow-up shots and improved accuracy. The ability to switch modes on the fly means you're never locked into one firing method—adapt to your situation instantly.
