Franklin Armory brings its patented Binary Firing System to your Glock 17 Gen3 with the new G-S173! This innovative system allows you to seamlessly switch between semiautomatic and Binary modes, offering reduced split times and tighter groupings. Just like all BFS triggers, canceling the release round is as easy as switching back to semiautomatic while keeping the trigger depressed. The integrated back plate mode indicator ensures you always know which mode you're in without losing sight of your target. Perfect for defense, sporting, and recreational use.
