Franklin Armory Binary Firing System for Glock G17 Gen 3 Pistols - G-S173

Franklin Armory G-S173: 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. Perfect for defense, sporting and recreational use.
