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.
