Franklin Armory G-S173 Binary Trigger Kit for Glock 17 Gen3

The Franklin Armory G-S173 Binary Trigger Kit for Glock 17 Gen3 transforms your pistol with a dual-fire-mode trigger system designed for shooters who want flexibility without sacrificing reliability. This drop-in kit lets you toggle between traditional semiautomatic and binary operation, giving you tighter splits and faster follow-up shots on demand—ideal for competitive shooters, recreational range days, and defensive training where round counts matter.

Installation is straightforward; the G-S173 fits Glock 17 Gen3 frames with no gunsmithing required. The integrated mode indicator on the backplate keeps you informed of your current firing mode without breaking sight picture, and the selector is intuitive to operate under stress. If you need to cancel a round while the trigger is held in binary mode, simply flip back to semiauto while depressed—no need to release and re-engage.

Built with serious shooters in mind, the trigger assembly includes front and rear tritium night sights for low-light performance, plus high-tactile serrations on the grip surfaces and anti-glare top stripe serrations to reduce reflection. The kit is optics-ready, meaning you can mount a red dot or other pistol optic with compatible adapter plates (sold separately). Whether you're training for competition, honing defensive skills, or just running high-volume practice sessions, the G-S173 gives you the firing options to match your shooting discipline.
