Franklin Armory 1750000BLK G-S173 Binary Black Fits Glock 17 Gen 3

Franklin Armory’s Binary Firing System (BFS) is now available for Glock 17 Gen3.

Like all BFS triggers, the release round can be cancelled by simply switching back to semiautomatic while the trigger is depressed. Plus, always know which mode youre in without having to come off target with the integrated back plate mode indicator. Perfect for defense, sporting and recreational use.
