Franklin Armory's patented Binary Firing System (BFS) is now available for your Glock 19 Gen3! The new G-S193 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, youll always know which mode youre in without having to come off your target with the integrated back plate mode indicator. Perfect for defense, sporting and recreational use.
