That would be handy since mine is permanently jammed in a non-functioning state.

Is this the GK release we are talking about? It is junk in my opinion. The way to solve target panic is not by providing you with a whole bunch more stuff to think of. Squeezing the trigger isn't the best solution, though I was just thinking about that today in the context of a deliberative style. But in general you want backtension. On the odd occasion where you need to cruch the trigger, if you have good release habits, you will probably get away with it.
