...I guess once you pull it and hold it what happens if a cold range or other issue caused you not to want to do the release?
I never heard of the binary trigger until today, but looking at Franklin's website, it appears it comes with semi-auto and binary options. If you are in binary mode and don't want to "release" the second shot, you flip the selector to semi-auto or safe, which disconnects something so you can release the trigger without firing a shot.
