Franklin Armory

Franklin Armory's patented Binary Firing System (BFS) is now available for your Glock 17 Gen3! The new G-S173 allows you to select between semiautomatic and Binary modes to provide reduced split times and tighter groupings. Like all BFS triggers the release round can be cancelled by simply switching back to semiautomatic while the trigger is depressed. Plus you'll always know which mode you're in without having to come off your target with the integrated back plate mode indicator. Prefect for defense sporting and recreational use. - Features: - Easy to install - Fits Glock 17 Gen3 - Selectable Semi and Binary (pull and release) - Integrated mode indicator - Optics ready (custom adapter plates sold separately) - Front and rear tritium night sights - High-tactile front and rear serrations - Anti-glare top stripe serrations - Binary Trigger Operation: - Position 1-Semi Fires 1 round per pull - Position 2- Binary Fires 1 round on pull and 1 round on release
