Exclusive Blue Franklin Armory G-S173 Glock Binary Firing System Kit – For Glock 17 Gen 3


All Sales are Final. No Returns, No Refunds, No exchanges.

In Binary mode, a single round is fired when the trigger is pulled and a single round is fired when the trigger is released. One of the revered safety features incorporated into all Franklin Armory BFS™ triggers is the ability to cancel the release round. To cancel the release round on G-S173, simply move the selector lever located on the slide from Binary to the “semi” position before releasing the trigger.
