I didn't know that it was a recognized technique. Years ago I broke the last joint on my "bird" finger. The result is that I can only partially bend that fingertip. It's a royal pain when shooting handguns and I have to modify my grip somehow to compensate with many handguns. I have often considered the notion of resting my trigger finger alongside the frame and using that broken finger to actually pull the trigger. I may well try it now.
